      ocfs2: submit disk heartbeat bio using WRITE_SYNC · e873fdb5
      Noboru Iwamatsu authored
      Under heavy I/O load, writing the disk heartbeat can be forced to wait for
      minutes, and this causes the node to be fenced.
      
      This patch tries to use WRITE_SYNC in submitting the heartbeat bio, so
      that writing the heartbeat will have a priority over other requests.

      ocfs2: xattr: fix inlined xattr reflink · ef962df0
      Junxiao Bi authored
      Inlined xattr shared free space of inode block with inlined data or data
      extent record, so the size of the later two should be adjusted when
      inlined xattr is enabled.  See ocfs2_xattr_ibody_init().  But this isn't
      done well when reflink.  For inode with inlined data, its max inlined
      data size is adjusted in ocfs2_duplicate_inline_data(), no problem.  But
      for inode with data extent record, its record count isn't adjusted.  Fix
      it, or data extent record and inlined xattr may overwrite each other,
      then cause data corruption or xattr failure.
      
      One panic caused by this bug in our test environment is the following:

      ocfs2: fix readonly issue in ocfs2_unlink() · b5a8bb71
      Younger Liu authored
      While deleting a file with ocfs2_unlink(), there is a bug in this
      function.  This bug will result in filesystem read-only.
      
      After calling ocfs2_orphan_add(), the file which will be deleted is
      added into orphan dir.  If ocfs2_delete_entry() fails, the file still
      exists in the parent dir.  And this scenario introduces a conflict of
      metadata.
      
      If a file is added into orphan dir, when we put inode of the file with
      iput(), the inode i_flags is setted (~OCFS2_VALID_FL) in
      ocfs2_remove_inode(), and then write back to disk.
      
      But as previously mentioned, the file still exists in the parent dir.
      On other nodes, the file can be still accessed.  When first read the
      file with ocfs2_read_blocks() from disk, It will check and avalidate
      inode using ocfs2_validate_inode_block().  So File system will be
      readonly because the inode is invalid.  In other words, the inode
      i_flags has been set (~OCFS2_VALID_FL).

      ocfs2: rework transaction rollback in ocfs2_relink_block_group() · 49309841
      Jie Liu authored
      In ocfs2_relink_block_group(), we roll back all those changes if notify
      intent to modify buffers for metadata update failed even if the relevant
      buffer has not yet been modified/got dirty at that point, that are not
      quite right because of:
      
       - None buffer has been modified/dirty if failed to call
         ocfs2_journal_access_gd() against the previous block group buffer
      
       - Only the previous block group buffer has got dirty if failed to call
         ocfs2_journal_access_gd() against the block group buffer
      
       - There is no need to roll back the change for file entry buffer at all
      
      Those problems will not cause anything wrong but unnecessary.  This
      patch fix them and kill the useless bg_ptr variable as well.

      ocfs2: need rollback when journal_access failed in ocfs2_orphan_add() · ea45466a
      Younger Liu authored
      While adding a file into orphan dir in ocfs2_orphan_add(), it calls
      __ocfs2_add_entry() before ocfs2_journal_access_di().  If
      ocfs2_journal_access_di() failed, the file is added into orphan dir, and
      orphan dir dinode updated, but file dinode has not been updated.
      Accordingly, the data is not consistent between file dinode and orphan
      dir.
      
      So, need to call ocfs2_journal_access_di() before __ocfs2_add_entry(),
      and if ocfs2_journal_access_di() failed, orphan_fe and
      orphan_dir_inode->i_nlink need rollback.
      
      This bug was added by 3939fda4 ("Ocfs2: Journaling i_flags and
      i_orphaned_slot when adding inode to orphan dir.").

      ocfs2: dlmlock_master() should return DLM_NORMAL after adding lock to blocked list · 096b2ef8
      Xue jiufei authored
      dlmlock_master() returns DLM_RECOVERING/DLM_MIGRATING/ DLM_FORWAR after
      adding lock to blocked list if lockres has the state
      DLM_LOCK_RES_RECOVERING/DLM_LOCK_RES_MIGRATING/ DLM_LOCK_RES_IN_PROGRESS.
      so it will retry in dlmlock().  And this may cause dlm_thread fall into an
      infinite loop
      
      	Thread1                                  dlm_thread
      
        calls dlm_lock->dlmlock_master,
        if lockresA is in state
        DLM_LOCK_RES_RECOVERING, calls
        __dlm_wait_on_lockres() and waits
        until others threads clear this
        state;
      
        If cannot grant this lock,
        adding lock to blocked list,
        and return DLM_RECOVERING;
      
                                              Grant this lock and move it to
                                              grant list;
      
        After a while, retry and
        calls list_add_tail(), adding lock
        to blocked list again.
      
      Granted and blocked list of this lockres will become the following
      conditions:
      
          lock_res->granted.next = dlm_lock->list_head;
          lock_res->blocked.next = dlm_lock->list_head;
          dlm_lock->list_head.next = dlm_lock_resource->blocked;
      
      When dlm_thread traverses the granted list, it will fall into an endless
      loop, checking dlm_lock.list_head, dlm_lock->list_head.next
      (i.e.lock_res->blocked), lock_res->blocked.next(i.e.dlm_lock.list_head
      again) .....

      configfs: use capped length for ->store_attribute() · 7121064b
      Dan Carpenter authored
      The difference between "count" and "len" is that "len" is capped at
      4095.  Changing it like this makes it match how sysfs_write_file() is
      implemented.
      
      This is a static analysis patch.  I haven't found any store_attribute()
      functions where this change makes a difference.

      This required inclusion of irqflags.h, which broke ia64 and mn10300 (at

      Switch on_each_cpu() back to a macro to fix this.

       "This contains the usual updates from other people (listed below) and
        the usual random muddle of miscellaneous ARM updates which cover some
        low priority bug fixes and performance improvements.
      
        I've started to put the pull request wording into the merge commits,
        which are:
      
         - NoMMU stuff:
      
           This includes the following series sent earlier to the list:
            - nommu-fixes
            - R7 Support
            - MPU support
      
           I've left out the ARCH_MULTIPLATFORM/!MMU stuff that Arnd and I
           were discussing today until we've reached a conclusion/that's had
           some more review.
      
           This is rebased (and re-tested) on your devel-stable branch because
           otherwise there were going to be conflicts with Uwe's V7M work now
           that you've merged that.  I've included the fix for limiting MPU to
           CPU_V7.
      
         - Huge page support
      
           These changes bring both HugeTLB support and Transparent HugePage
           (THP) support to ARM.  Only long descriptors (LPAE) are supported
           in this series.
      
           The code has been tested on an Arndale board (Exynos 5250).
      
         - LPAE updates
      
           Please pull these miscellaneous LPAE fixes I've been collecting for
           a while now for 3.11.  They've been tested and reviewed by quite a
           few people, and most of the patches are pretty trivial.  -- Will Deacon.
      
         - arch_timer cleanups
      
           Please pull these arch_timer cleanups I've been holding onto for a
           while.  They're the same as my last posting, but have been rebased
           to v3.10-rc3.
      
         - mpidr linearisation (multiprocessor id register - identifies which
           CPU number we are in the system)
      
           This patch series that implements MPIDR linearization through a
           simple hashing algorithm and updates current cpu_{suspend}/{resume}
           code to use the newly created hash structures to retrieve context
           pointers.  It represents a stepping stone for the implementation of
           power management code on forthcoming multi-cluster ARM systems.
      
           It has been tested on TC2 (dual cluster A15xA7 system), iMX6q,
           OMAP4 and Tegra, with processors hitting low-power states requiring
           warm-boot resume through the cpu_resume code path"

      vfs: export lseek_execute() to modules · 46a1c2c7
      Jie Liu authored
      For those file systems(btrfs/ext4/ocfs2/tmpfs) that support
      SEEK_DATA/SEEK_HOLE functions, we end up handling the similar
      matter in lseek_execute() to update the current file offset
      to the desired offset if it is valid, ceph also does the
      simliar things at ceph_llseek().
      
      To reduce the duplications, this patch make lseek_execute()
      public accessible so that we can call it directly from the
      underlying file systems.
      
      Thanks Dave Chinner for this suggestion.

       "This pull request contains the following changes.
      
         - cgroup_subsys_state (css) reference counting has been converted to
           percpu-ref.  css is what each resource controller embeds into its
           own control structure and perform reference count against.  It may
           be used in hot paths of various subsystems and is similar to module
           refcnt in that aspect.  For example, block-cgroup's css refcnting
           was showing up a lot in Mikulaus's device-mapper scalability work
           and this should alleviate it.
      
         - cgroup subtree iterator has been updated so that RCU read lock can
           be released after grabbing reference.  This allows simplifying its
           users which requires blocking which used to build iteration list
           under RCU read lock and then traverse it outside.  This pull
           request contains simplification of cgroup core and device-cgroup.
           A separate pull request will update cpuset.

      Pull workqueue changes from Tejun Heo:
       "Surprisingly, Lai and I didn't break too many things implementing
        custom pools and stuff last time around and there aren't any follow-up
        changes necessary at this point.
      
        The only change in this pull request is Viresh's patches to make some
        per-cpu workqueues to behave as unbound workqueues dependent on a boot
        param whose default can be configured via a config option.  This leads
        to higher processing overhead / lower bandwidth as more work items are
        bounced across CPUs; however, it can lead to noticeable powersave in
        certain configurations - ~10% w/ idlish constant workload on a
        big.LITTLE configuration according to Viresh.
      
        This is because per-cpu workqueues interfere with how the scheduler
        perceives whether or not each CPU is idle by forcing pinned tasks on
        them, which makes the scheduler's power-aware scheduling decisions
        less effective.
      
        Its effectiveness is likely less pronounced on homogenous
        configurations and this type of optimization can probably be made
        automatic; however, the changes are pretty minimal and the affected
        workqueues are clearly marked, so it's an easy gain for some
        configurations for the time being with pretty unintrusive changes."

       "This pull request contains Kent's per-cpu reference counter.  It has
        gone through several iterations since the last time and the dynamic

        The usual usage is relatively straight-forward although async kill
        confirm interface, which is not used int most cases, is somewhat icky.
        There also are some interface concerns - e.g.  I'm not sure about
        passing in @relesae callback during init as that becomes funny when we
        later implement synchronous kill_and_drain - but nothing too serious
        and it's quite useable now.
      
        cgroup_subsys_state refcnting has already been converted and we should
        convert module refcnt (Kent?)"
