#     Merge tag 'locks-v4.21-1' of git://git.kernel.org/pub/scm/linux/kernel/git/jlayton/linux
#     
#     Pull file locking updates from Jeff Layton:
#      "The main change in this set is Neil Brown's work to reduce the
#       thundering herd problem when a heavily-contended file lock is
#       released.
#     
#       Previously we'd always wake up all waiters when this occurred. With
#       this set, we'll now we only wake up waiters that were blocked on the
#       range being released"
#     
#     * tag 'locks-v4.21-1' of git://git.kernel.org/pub/scm/linux/kernel/git/jlayton/linux:
#       locks: Use inode_is_open_for_write
#       fs/locks: remove unnecessary white space.
#       fs/locks: merge posix_unblock_lock() and locks_delete_block()
#       fs/locks: create a tree of dependent requests.
#       fs/locks: change all *_conflict() functions to return bool.
#       fs/locks: always delete_block after waiting.
#       fs/locks: allow a lock request to block other requests.
#       fs/locks: use properly initialized file_lock when unlocking.
#       ocfs2: properly initial file_lock used for unlock.
#       gfs2: properly initial file_lock used for unlock.
#       NFS: use locks_copy_lock() to copy locks.
#       fs/locks: split out __locks_wake_up_blocks().
#       fs/locks: rename some lists and pointers.
