Pull dlm updates from David Teigland:

- Allow blocking posix lock requests to be interrupted while waiting.
This requires a cancel request to be sent to the userspace daemon
where posix lock requests are processed across the cluster.

- Fix a posix lock patch from the previous cycle in which lock requests
from different file systems could be mixed up.

- Fix some long standing problems with nfs posix lock cancelation.

- Add a new debugfs file for printing queued callbacks.

- Stop modifying buffers that have been used to receive a message.

- Misc cleanups and some refactoring.

fs: dlm: don't use RCOM_NAMES for version detection

Currently RCOM_STATUS and RCOM_NAMES inclusive their replies are being
used to determine the DLM version. The RCOM_NAMES messages are triggered
in DLM recovery when calling dlm_recover_directory() only. At this time
the DLM version need to be determined. I ran some tests and did not
expirenced some issues. When the DLM version detection was developed
probably I run once in a case of RCOM_NAMES and the version was not
detected yet. However it seems to be not necessary.

For backwards compatibility we still need to accept RCOM_NAMES messages
which are not protected regarding the DLM message reliability layer aka
stateless message. This patch changes that RCOM_NAMES we are sending out
after this patch are not stateless anymore.

Currently dlm_recover_master_copy() manipulates the receive buffer of an

new rcom message with the same message has those new values. This patch
avoids manipulating the received rcom message by store the values for
the new rcom message in paremter assigned with call by reference. Later
when dlm_send_rcom_lock() constructs a new message and memcpy() the
receive buffer those values will be set on the new constructed message.

This patch removes a read of the ls->ls_recover_seq uint64_t number in
_create_rcom(). If the ls->ls_recover_seq is readed the ls_recover_lock
need to held. However this number was always readed before when any rcom
message is received and it's not necessary to read it again from a per
lockspace variable to use it for the replying message. This patch will
pass the sequence number as parameter so another read of ls->ls_recover_seq
and holding the ls->ls_recover_lock is not required.

previously scheduled for removal

- Fix a bug where the pending callback flag would be incorrectly
cleared, which could potentially result in missing a completion
callback

- Use an unbound workqueue for dlm socket handling so that socket
operations can be processed with less delay

- Fix possible lockspace join connection errors with large clusters
(e.g. over 16 nodes) caused by a small socket backlog setting

- Use atomic bit ops for internal flags to help avoid mistakes copying
flag values from messages

- Fix recently introduced bug where memory for lvb data could be
unnecessarily allocated for a lock

fs: dlm: change dflags to use atomic bits

Currently manipulating lkb_dflags assumes to held the rsb lock assigned
to the lkb. This is held by dlm message processing after certain
time to lookup the right rsb from the received lkb message id. For user
space locks flags, which is currently the only use case for lkb_dflags,
flags are also being set during dlm character device handling without
holding the rsb lock. To minimize the risk that bit operations are
getting corrupted we switch to atomic bit operations. This patch will
also introduce helpers to snapshot atomic bit values in an non atomic
way. There might be still issues with the flag handling e.g. running in
case of manipulating bit ops and snapshot them at the same time, but this
patch minimize them and will start to use atomic bit operations.
