Pull dlm updates from David Teigland:
 "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"
