dlm: prevent connections during shutdown

2012-04-26T20:35:38+00:00

During lowcomms shutdown, a new connection could possibly
be created, and attempt to use a workqueue that's been
destroyed.  Similarly, during startup, a new connection
could attempt to use a workqueue that's not been set up
yet.  Add a global variable to indicate when new connections
are allowed.

Merge tag 'dlm-3.4' of git://git.kernel.org/pub/scm/linux/kernel/git/teigland/linux-dlm

2012-03-21T20:54:22+00:00

Pull dlm updates for 3.4 from David Teigland:
 "This set includes one trivial fix, and one simple recovery speed up.
  Directory recovery can use the standard hash table to find resources
  rather than always searching the linear recovery list."

* tag 'dlm-3.4' of git://git.kernel.org/pub/scm/linux/kernel/git/teigland/linux-dlm:

dlm: last element of dlm_local_addr[] never used

2012-03-21T14:18:34+00:00

The last element of dlm_local_addr[DLM_MAX_ADDR_COUNT]
was not used because the loop ended at COUNT - 1.

dlm: use single thread workqueues

2011-02-11T22:50:47+00:00

The recent commit to use cmwq for send and recv threads
dcce240ead802d42b1e45ad2fcb2ed4a399cb255 introduced problems,
apparently due to multiple workqueue threads.  Single threads
make the problems go away, so return to that until we fully
understand the concurrency issues with multiple threads.

dlm: sanitize work_start() in lowcomms.c

The create_workqueue() returns NULL if failed rather than ERR_PTR().
Fix error checking and remove unnecessary variable 'error'.
