Remove the definition of struct client_obd_lock and the functions client_obd_list_{init,lock,unlock,done}(). Use spinlock_t for the cl_{loi,lru}_list_lock members of struct client_obd and call spin_{lock,unlock}() directly. Signed-off-by: -

In struct ll_inode_info remove the struct ost_lvb lli_lvb member and replace it with obd_time lli_{a,m,c}time. Rename ll_merge_lvb() to ll_merge_attr(). Remove cl_merge_lvb() and replace calls to it with calls to ll_merge_attr(). Signed-off-by:Bobi Jam <bobijam@gmail.com> Reviewed-by:

It used to check each page in the readahead window is covered by a lock underneath, now cpo_page_is_under_lock() provides @max_index to help decide the maximum ra window. @max_index can be modified by OSC to extend the maximum lock region, to align stripe boundary at LOV, and to make sure the readahead region at least covers read region at LLITE layer. After this is done, usually readahead code calls cpo_page_is_under_lock() for each stripe. Signed-off-by:

Use weigh_ast to decide if a lock covers any pages. In recovery, weigh_ast will be used to decide if a DLM read lock covers any locked pages, or it will be canceled instead being recovered. The problem with the original implementation is that it attached each osc_page to an osc_lock also changed lock state to add every pages for readahead. Signed-off-by:

in ll_write_end(), instead of adding the page into writeback cache directly, it will be held in a page list. After enough pages have been collected, issue them all with cio_commit_async(). Signed-off-by:

This change adds support for a single preallocated cl_env per CPU which can be used in circumstances where reschedule is not possible. Currently this interface is only used by the ll_releasepage function. Signed-off-by:

This reverts a patch that was merged before lustre client was introduced into the stagign tree, so it's not in the history. The performance dropped a lot when memory reclaim process kicked in as ll_releasepage() was called to destroy lustre pages. It turned out that big overhead to allocate cl_env and keys on the fly so we have to revert this patch. The original problem for the reverted patch would be solved in a follow on patch instead.

CFS_PAGE_MASK is the same as PAGE_MASK, so get rid of it. We are replacing it with PAGE_MASK instead of PAGE_CACHE_MASK because PAGE_CACHE_* stuff is apparently going away. Signed-off-by:

Allocating a big hash table using the formula for osd does not really work for clients. We will create new hash table for each mount on a single client which is a lot of memory more than expected. This patch limits the hash table up to 8M which has 524288 entries Signed-off-by:

This function assumes that the async subdevice has a cancel() function. It looks like all the current comedi drivers implement a cancel() for the async subdevices except for the dt2814 analog input usbdevice. Fix comedi_handle_events() so it does not try to call a non-existent cancel() function. Add a dev_warn() to __comedi_device_postconfig_async() so that any new driver authors will be reminded to implement the cancel(). Signed-off-by:

timed_output was only used by the Android vibrator HAL which has now learned how to use LED triggers instead[1]. Any users of it in AOSP are on ancient kernels. Adding support for LED triggers is purely DT changes and proper kernel config.
