[PATCH 0/4] filelock: WARN when @filp and fl_file don't match

[Jeff Layton <jlayton@kernel.org>]

Eventually, I'd like to reduce the redundant arguments to the locking
APIs, but to get there we need to ensure the callers all set their file
locks sanely.

Adding the WARN_ON_ONCEs helped to find a couple of warts in lockd's
file handling. The first 3 patches fix those.

I'd like to see these included in v6.2, with an eye toward a locking API
cleanup in v6.3.

Thanks,

Jeff Layton (4):
  lockd: set missing fl_flags field when retrieving args
  lockd: ensure we use the correct file description when unlocking
  lockd: fix file selection in nlmsvc_cancel_blocked
  filelock: WARN_ON_ONCE when ->fl_file and filp don't match
