Merge tag 'dlm-6.2' of git://git.kernel.org/pub/scm/linux/kernel/git/teigland/linux-dlm

Pull dlm updates from David Teigland:
 "These patches include the usual cleanups and minor fixes, the removal
  of code that is no longer needed due to recent improvements, and
  improvements to processing large volumes of messages during heavy
  locking activity.

  Summary:

   - Misc code cleanup

   - Fix a couple of socket handling bugs: a double release on an error
     path and a data-ready race in an accept loop

   - Remove code for resending dir-remove messages. This code is no
     longer needed since the midcomms layer now ensures the messages are
     resent if needed

   - Add tracepoints for dlm messages

   - Improve callback queueing by replacing the fixed array with a list

   - Simplify the handling of a remove message followed by a lookup
     message by sending both without releasing a spinlock in between

   - Improve the concurrency of sending and receiving messages by
     holding locks for a shorter time, and changing how workqueues are
     used

   - Remove old code for shutting down sockets, which is no longer
     needed with the reliable connection handling that was recently
     added"
