David Teigland 81456807a3 [DLM] schedule during long loop through locks
The loop through all waiting locks in recover_waiters can potentially be
long, so we should schedule explicitly.

David Teigland 2b4e926aab [DLM] fix loop in grant_after_purge
The loop in grant_after_purge is intended to find all rsb's in each hash
bucket that have the LOCKS_PURGED flag set.  The loop was quitting the
current bucket after finding just one rsb instead of going until there are
no more.

David Teigland 597d0cae0f [DLM] dlm: user locks
This changes the way the dlm handles user locks.  The core dlm is now
aware of user locks so they can be dealt with more efficiently.  There is
no more dlm_device module which previously managed its own duplicate copy
of every user lock.

David Teigland 97a35d1e5f [DLM] fix grant_after_purge softlockup
In dlm_grant_after_purge() we were holding a hash table read_lock while
calling put_rsb() which potentially removes the rsb from the hash table,
taking the same lock in write.  Fix this by flagging rsb's ahead of time
that have been purged.  Then iteratively read_lock the hash table, find a
flagged rsb, unlock, process rsb.

David Teigland b3f58d8f2b [DLM] Pass in lockspace to lkb put function
In some cases a lockspace isn't attached to the lkb, so that
it needs to be passed directly to the lkb put function.

David Teigland e7fd41792f [DLM] The core of the DLM for GFS2/CLVM
This is the core of the distributed lock manager which is required
to use GFS2 as a cluster filesystem. It is also used by CLVM and
can be used as a standalone lock manager independantly of either
of these two projects.

It implements VAX-style locking modes.
