cgroup is transitioning to using css (cgroup_subsys_state) as the main subsys interface handle instead of cgroup and the iterators will be updated to use css too. The iterators need to walk the cgroup hierarchy and return the css's matching the origin css, which is a bit cumbersome to open code. This patch converts cgroup_next_sibling() to cgroup_next_child() so that it can handle all steps of direct child iteration. This will be used to update iterators to take @css instead of @cgrp. In addition to the new iteration init handling, cgroup_next_child() is restructured so that the different branches share the end of iteration condition check. This patch doesn't change any behavior.

cgroup is currently in the process of transitioning to using struct cgroup_subsys_state * as the primary handle instead of struct cgroup. Please see the previous commit which converts the subsystem methods for rationale. This patch converts all cftype file operations to take @css instead of @cgroup. cftypes for the cgroup core files don't have their subsytem pointer set. These will automatically use the dummy_css added by the previous patch and can be converted the same way. Most subsystem conversions are straight forwards but there are some interesting ones. * freezer: update_if_frozen() is also converted to take @css instead of @cgroup for consistency. This will make the code look simpler too once iterators are converted to use css. * memory/vmpressure: mem_cgroup_from_css() needs to be exported to vmpressure while mem_cgroup_from_cont() can be made static. Updated accordingly. * cpu: cgroup_tg() doesn't have any user left. Removed. * cpuacct: cgroup_ca() doesn't have any user left. Removed. * hugetlb: hugetlb_cgroup_form_cgroup() doesn't have any user left. Removed. * net_cls: cgrp_cls_state() doesn't have any user left. Removed. Signed-off-by:

cgroup subsystem API is being converted to use css (cgroup_subsys_state) as the main handle, which makes things a bit awkward for subsystem agnostic core features - the "cgroup.*" interface files and various iterations - a bit awkward as they don't have a css to use. This patch adds cgroup->dummy_css which has NULL ->ss and whose only role is pointing back to the cgroup. This will be used to support subsystem agnostic features on the coming css based API. css_parent() is updated to handle dummy_css's. Note that css will soon grow its own ->parent field and css_parent() will be made trivial. Signed-off-by:

Previously, each file read/write operation relied on the inode reference count pinning the cgroup and simply checked whether the cgroup was marked dead before proceeding to invoke the per-subsystem callback. This was rather silly as it didn't have any synchronization or css pinning around the check and the cgroup may be removed and all css refs drained between the DEAD check and actual method invocation. This patch pins the css between open() and release() so that it is guaranteed to be alive for all file operations and remove the silly DEAD checks from cgroup_file_read/write(). Signed-off-by:

cgroup is transitioning to using css (cgroup_subsys_state) instead of cgroup as the primary subsystem handle. The cgroupfs file interface will be converted to use css's which requires finding out the subsystem from cftype so that the matching css can be determined from the cgroup. This patch adds cftype->ss which points to the subsystem the file belongs to. The field is initialized while a cftype is being registered. This makes it unnecessary to explicitly specify the subsystem for other cftype handling functions. @ss argument dropped from various cftype handling functions. This patch shouldn't introduce any behavior differences. Signed-off-by:

cgroup is currently in the process of transitioning to using struct cgroup_subsys_state * as the primary handle instead of struct cgroup * in subsystem implementations for the following reasons. * With unified hierarchy, subsystems will be dynamically bound and unbound from cgroups and thus css's (cgroup_subsys_state) may be created and destroyed dynamically over the lifetime of a cgroup, which is different from the current state where all css's are allocated and destroyed together with the associated cgroup. This in turn means that cgroup_css() should be synchronized and may return NULL, making it more cumbersome to use. * Differing levels of per-subsystem granularity in the unified hierarchy means that the task and descendant iterators should behave differently depending on the specific subsystem the iteration is being performed for. * In majority of the cases, subsystems only care about its part in the cgroup hierarchy - ie. the hierarchy of css's. Subsystem methods often obtain the matching css pointer from the cgroup and don't bother with the cgroup pointer itself. Passing around css fits much better. This patch converts all cgroup_subsys methods to take @css instead of @cgroup. The conversions are mostly straight-forward. A few noteworthy changes are * ->css_alloc() now takes css of the parent cgroup rather than the pointer to the new cgroup as the css for the new cgroup doesn't exist yet. Knowing the parent css is enough for all the existing subsystems. * In kernel/cgroup.c::offline_css(), unnecessary open coded css dereference is replaced with local variable access. This patch shouldn't cause any behavior differences. v2: Unnecessary explicit cgrp->subsys[] deref in css_online() replaced with local variable @css as suggested by Li Zefan. Rebased on top of new for-3.12 which includes for-3.11-fixes so that ->css_free() invocation added by da0a12ca ("cgroup: fix a leak when percpu_ref_init() fails") is converted too.

Currently, controllers have to explicitly follow the cgroup hierarchy to find the parent of a given css. cgroup is moving towards using cgroup_subsys_state as the main controller interface construct, so let's provide a way to climb the hierarchy using just csses. This patch implements css_parent() which, given a css, returns its parent. The function is guarnateed to valid non-NULL parent css as long as the target css is not at the top of the hierarchy. freezer, cpuset, cpu, cpuacct, hugetlb, memory, net_cls and devices are converted to use css_parent() instead of accessing cgroup->parent directly. * __parent_ca() is dropped from cpuacct and its usage is replaced with parent_ca(). The only difference between the two was NULL test on cgroup->parent which is now embedded in css_parent() making the distinction moot. Note that eventually a css->parent field will be added to css and the NULL check in css_parent() will go away. This patch shouldn't cause any behavior differences. Signed-off-by:

css (cgroup_subsys_state) is usually embedded in a subsys specific data structure. Subsystems either use container_of() directly to cast from css to such data structure or has an accessor function wrapping such cast. As cgroup as whole is moving towards using css as the main interface handle, add and update such accessors to ease dealing with css's. All accessors explicitly handle NULL input and return NULL in those cases. While this looks like an extra branch in the code, as all controllers specific data structures have css as the first field, the casting doesn't involve any offsetting and the compiler can trivially optimize out the branch. * blkio, freezer, cpuset, cpu, cpuacct and net_cls didn't have such accessor. Added. * memory, hugetlb and devices already had one but didn't explicitly handle NULL input. Updated. Signed-off-by:

Currently, given a cgroup_subsys_state, there's no way to find out which subsystem the css is for, which we'll need to convert the cgroup controller API to primarily use @css instead of @cgroup. This patch adds cgroup_subsys_state->ss which points to the subsystem the @css belongs to. While at it, remove the comment about accessing @css->cgroup to determine the hierarchy. cgroup core will provide API to traverse hierarchy of css'es and we don't want subsystems to directly walk cgroup hierarchies anymore.

The names of the two struct cgroup_subsys_state accessors - cgroup_subsys_state() and task_subsys_state() - are somewhat awkward. The former clashes with the type name and the latter doesn't even indicate it's somehow related to cgroup. We're about to revamp large portion of cgroup API, so, let's rename them so that they're less awkward. Most per-controller usages of the accessors are localized in accessor wrappers and given the amount of scheduled changes, this isn't gonna add any noticeable headache. Rename cgroup_subsys_state() to cgroup_css() and task_subsys_state() to task_css(). This patch is pure rename. Signed-off-by:

rebind_subsystems() performs santiy checks even on subsystems which aren't specified to be added or removed and the checks aren't all that useful given that these are in a very cold path while the violations they check would trip up in much hotter paths. Let's remove these from rebind_subsystems(). Signed-off-by:

Module ref handling in cgroup is rather weird. parse_cgroupfs_options() grabs all the modules for the specified subsystems. A module ref is kept if the specified subsystem is newly bound to the hierarchy. If not, or the operation fails, the refs are dropped. This scatters module ref handling across multiple functions making it difficult to track. It also make the function nasty to use for dynamic subsystem binding which is necessary for the planned unified hierarchy. There's nothing which requires the subsystem modules to be pinned between parse_cgroupfs_options() and rebind_subsystems() in both mount and remount paths. parse_cgroupfs_options() can just parse and rebind_subsystems() can handle pinning the subsystems that it wants to bind, which is a natural part of its task - binding - anyway. Move module ref handling into rebind_subsystems() which makes the code a lot simpler - modules are gotten iff it's gonna be bound and put iff unbound or binding fails. v2: Li pointed out that if a controller module is unloaded between parsing and binding, rebind_subsystems() won't notice the missing controller as it only iterates through existing controllers. Fix it by updating rebind_subsystems() to compare @added_mask to @pinned and fail with -ENOENT if they don't match. Signed-off-by:

task_cgroup_path_from_hierarchy() was added for the planned new users and none of the currently planned users wants to know about multiple hierarchies. This patch drops the multiple hierarchy part and makes it always return the path in the first non-dummy hierarchy. As unified hierarchy will always have id 1, this is guaranteed to return the path for the unified hierarchy if mounted; otherwise, it will return the path from the hierarchy which happens to occupy the lowest hierarchy id, which will usually be the first hierarchy mounted after boot.

rebind_subsystems() currently fails if the hierarchy has any !root cgroups; however, on the planned unified hierarchy, rebind_subsystems() will be used while populated. Move the test to cgroup_remount(), which is the only place the test is necessary anyway. As it's impossible for the other two callers of rebind_subsystems() to have populated hierarchy, this doesn't make any behavior changes. Signed-off-by:

Currently, creating and removing cgroup files in the root directory are handled separately from the actual subsystem binding and unbinding which happens in rebind_subsystems(). Also, rebind_subsystems() users aren't handling file creation errors properly. Let's integrate top_cgroup file handling into rebind_subsystems() so that it's simpler to use and everyone handles file creation errors correctly. * On a successful return, rebind_subsystems() is guaranteed to have created all files of the new subsystems and deleted the ones belonging to the removed subsystems. After a failure, no file is created or removed. * cgroup_remount() no longer needs to make explicit populate/clear calls as it's all handled by rebind_subsystems(), and it gets proper error handling automatically. * cgroup_mount() has been updated such that the root dentry and cgroup are linked before rebind_subsystems(). Also, the init_cred dancing and base file handling are moved right above rebind_subsystems() call and proper error handling for the base files is added. While at it, add a comment explaining what's going on with the cred thing. * cgroup_kill_sb() calls rebind_subsystems() to unbind all subsystems which now implies removing all subsystem files which requires the directory's i_mutex. Grab it. This means that files on the root cgroup are removed earlier - they used to be deleted from generic super_block cleanup from vfs. This doesn't lead to any functional difference and it's cleaner to do the clean up explicitly for all files. Combined with the previous changes, this makes all cgroup file creation errors handled correctly. v2: Added comment on init_cred. v3: Li spotted that cgroup_mount() wasn't freeing tmp_links after base file addition failure. Fix it by adding free_tmp_links error handling label. v4: v3 introduced build bugs which got noticed by Fengguang's awesome kbuild test robot. Fixed, and shame on me. Signed-off-by: -

rebind_subsystems() will be updated to handle file creations and removals with proper error handling and to do that will need to perform file operations before actually adding the subsystem to the hierarchy. To enable such usage, update cgroup_populate/clear_dir() to use for_each_subsys() instead of for_each_root_subsys() so that they operate on all subsystems specified by @subsys_mask whether that subsystem is currently bound to the hierarchy or not.

cgroup_populate_dir() didn't use to check whether the actual file creations were successful and could return success with only subset of the requested files created, which is nasty. This patch udpates cgroup_populate_dir() so that it either succeeds with all files or fails with no file. v2: The original patch also converted for_each_root_subsys() usages to for_each_subsys() without explaining why. That part has been moved to a separate patch. Signed-off-by: -

cgroup_populate/clear_dir() currently take @base_files and adds and removes, respectively, cgroup_base_files[] to the directory. File additions and removals are being reorganized for proper error handling and more dynamic handling for the unified hierarchy, and mixing base and subsys file handling into the same functions gets a bit confusing. This patch moves base file handling out of cgroup_populate/clear_dir() into their users - cgroup_mount(), cgroup_create() and cgroup_destroy_locked(). Note that this changes the behavior of base file removal. If @base_files is %true, cgroup_clear_dir() used to delete files regardless of cftype until there's no files left. Now, only files with matching cfts are removed. As files can only be created by the base or registered cftypes, this shouldn't result in any behavior difference. Signed-off-by:

cgroup_add_cftypes() uses cgroup_cfts_commit() to actually create the files; however, both functions ignore actual file creation errors and just assume success. This can lead to, for example, blkio hierarchy with some of the cgroups with only subset of interface files populated after cfq-iosched is loaded under heavy memory pressure, which is nasty. This patch updates cgroup_cfts_commit() and cgroup_add_cftypes() to guarantee that all files are created on success and no file is created on failure. Signed-off-by:

cgroup_addrm_files() mishandled error return value from cgroup_add_file() and returns error iff the last file fails to create. As we're in the process of cleaning up file add/rm error handling and will reliably propagate file creation failures, there's no point in keeping adding files after a failure. Replace the broken error collection logic with immediate error return. While at it, add lockdep assertions and function comment. Signed-off-by:

* Rename it to cgroup_clear_dir() and make it take the pointer to the target cgroup instead of the the dentry. This makes the function consistent with its counterpart - cgroup_populate_dir(). * Move cgroup_clear_directory() invocation from cgroup_d_remove_dir() to cgroup_remount() so that the function doesn't have to determine the cgroup pointer back from the dentry. cgroup_d_remove_dir() now only deals with vfs, which is slightly cleaner.
