8f50eb9789 ocfs2/dlm: Cleanup lockres print
A previous patch added KERN_NOTICE to printks printing the lockres that
cluttered the output. This patch removes the log level. For people concerned
with syslog clutter, please note we now use this facility to print lockres
only during an error.

c834cdb157 ocfs2/dlm: Fix lockname in lockres print function
__dlm_print_one_lock_resource was printing lockname incorrectly.
Also, we now use printk directly instead of mlog as the latter prints
the line context which is not useful for this print.

74aa25856c ocfs2_dlm: Cookies in locks not being printed correctly in error messages
The dlm encodes the node number and a sequence number in the lock cookie.
It also stores the cookie in the lockres in the big endian format to avoid
swapping 8 bytes on each lock request. The bug here was that it was assuming
the cookie to be in the cpu format when decoding it for printing the error
message. This patch swaps the bytes before the print.

ba2bf21851 ocfs2_dlm: fix cluster-wide refcounting of lock resources
This was previously broken and migration of some locks had to be temporarily
disabled. We use a new (and backward-incompatible) set of network messages
to account for all references to a lock resources held across the cluster.
once these are all freed, the master node may then free the lock resource
memory once its local references are dropped.

3fb5a9891d [PATCH] fs/ocfs2/dlm/: cleanups
This patch #if 0's the no longer used dlm_dump_lock_resources().

Since this makes dlmdebug.h empty, this patch also removes this header.

Additionally, the needlessly global dlm_is_node_recovered() is made
static.

6714d8e86b [PATCH] OCFS2: The Second Oracle Cluster Filesystem
A distributed lock manager built with the cluster file system use case
in mind. The OCFS2 dlm exposes a VMS style API, though things have
been simplified internally. The only lock levels implemented currently
are NLMODE, PRMODE and EXMODE.
