Pull file locking updates from Jeff Layton:
 "The main change here is that I've broken out most of the file locking
  definitions into a new header file. I also went ahead and completed
  the removal of locks_inode function"

* tag 'locks-v6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/jlayton/linux:
  fs: remove locks_inode
  filelock: move file locking definitions to separate header file

- * note that the same struct is used to represent both a request for a lock and
- * the lock itself, but the same object is never used for both.
- *
- * FIXME: should we create a separate "struct lock_request" to help distinguish
- * these two uses?
- *
- * The varous i_flctx lists are ordered by:
- *
- * 1) lock owner
- * 2) lock range start
- * 3) lock range end
