ceph: don't re-send interrupted flock request

2017-07-07T15:25:13+00:00

Don't re-send interrupted flock request in cases of mds failover and receiving request forward. Because corresponding 'lock intr' request may have been finished, it won't get re-sent. Link: http://tracker.ceph.com/issues/20170 Signed-off-by: "Yan, Zheng" Signed-off-by: Ilya Dryomov

Move locks API users to locks_lock_inode_wait()

2015-10-22T18:57:36+00:00

Instead of having users check for FL_POSIX or FL_FLOCK to call the correct locks API function, use the check within locks_lock_inode_wait(). This allows for some later cleanup. Signed-off-by: Benjamin Coddington Signed-off-by: Jeff Layton

Revert "locks: keep a count of locks on the flctx lists"

2015-02-16T19:32:03+00:00

This reverts commit 9bd0f45b7037fcfa8b575c7e27d0431d6e6dc3bb. Linus rightly pointed out that I failed to initialize the counters when adding them, so they don't work as expected. Just revert this patch for now. Reported-by: Linus Torvalds Signed-off-by: Jeff Layton

This makes things a bit more efficient in the cifs and ceph lock pushing code. Signed-off-by: Jeff Layton Acked-by: Christoph Hellwig

locks: add a dedicated spinlock to protect i_flctx lists

2015-01-16T21:08:49+00:00

We can now add a dedicated spinlock without expanding struct inode. Change to using that to protect the various i_flctx lists. Signed-off-by: Jeff Layton Acked-by: Christoph Hellwig

ceph: move spinlocking into ceph_encode_locks_to_buffer and ceph_count_locks

2015-01-16T20:09:25+00:00

There is only a single call site for each of these functions, and the caller takes the i_lock prior to calling them and drops it just afterward. Move the spinlocking into the functions instead. Signed-off-by: Jeff Layton Acked-by: Christoph Hellwig
