Merge tag 'locks-v4.4-1' of git://git.samba.org/jlayton/linux
Pull file locking updates from Jeff Layton:
"The largest series of changes is from Ben who offered up a set to add
a new helper function for setting locks based on the type set in
fl_flags. Dmitry also send in a fix for a potential race that he
found with KTSAN"
* tag 'locks-v4.4-1' of git://git.samba.org/jlayton/linux:
locks: cleanup posix_lock_inode_wait and flock_lock_inode_wait
Move locks API users to locks_lock_inode_wait()
locks: introduce locks_lock_inode_wait()
locks: Use more file_inode and fix a comment
fs: fix data races on inode->i_flctx
locks: change tracepoint for generic_add_lease
