Subject: [GIT PULL] dlm updates for 6.5

Hi Linus,

Please pull dlm updates from tag:

git://git.kernel.org/pub/scm/linux/kernel/git/teigland/linux-dlm.git dlm-6.5

The dlm posix lock handling (for gfs2) has three notable changes:

- Local pids returned from GETLK are no longer negated.  A previous
  patch negating remote pids mistakenly changed local pids also.

- SETLKW operations can now be interrupted only when the process is
  killed, and not from other signals.  General interruption was
  resulting in previously acquired locks being cleared, not just
  the in-progress lock.  Handling this correctly will require
  extending a cancel capability to user space (a future feature.)

- If multiple threads are requesting posix locks (with SETLKW),
  fix incorrect matching of results to the requests.

The dlm networking has several minor cleanups, and one notable change:

- Avoid delaying ack messages for too long (used for message reliability),
  resulting in a backlog of un-acked messages.  These could previously
  be delayed as a result of either too many or too few other messages
  being sent.  Now an upper and lower threshold is used to determine
  when an ack should be sent.

Thanks,
Dave
