[DLM] keep dlm from panicing when traversing rsb list in debugfs This problem was originally reported against GFS6.1, but the same issue exists in upstream DLM. This patch keeps the rsb iterator assigning under the rsbtbl list lock. Each time we process an rsb we grab a reference to it to make sure it is not freed out from underneath us, and then put it when we get the next rsb in the list or move onto another list.

[GFS2] inode_diet: Replace inode.u.generic_ip with inode.i_private (gfs) The following patches reduce the size of the VFS inode structure by 28 bytes on a UP x86. (It would be more on an x86_64 system). This is a 10% reduction in the inode size on a UP kernel that is configured in a production mode (i.e., with no spinlock or other debugging functions enabled; if you want to save memory taken up by in-core inodes, the first thing you should do is disable the debugging options; they are responsible for a huge amount of bloat in the VFS inode structure). This patch: The filesystem or device-specific pointer in the inode is inside a union, which is pretty pointless given that all 30+ users of this field have been using the void pointer. Get rid of the union and rename it to i_private, with a comment to explain who is allowed to use the void pointer. This is just a cleanup, but it allows us to reuse the union 'u' for something something where the union will actually be used.

[DLM] dumping master locks Add a new debugfs file that dumps a compact list of mastered locks. This will be used by a userland daemon to collect state for deadlock detection. Also, for the existing function that prints all lock state, lock the rsb before going through the lock lists since they can be changing in the course of normal dlm activity.

[DLM] dump more lock values Add two more output fields (lkb_flags and rsb nodeid) to the new debugfs file that dumps one lock per line. Also, dump all locks instead of just mastered locks. Accordingly, use a suffix of _locks instead of _master. Signed-off-by: David Teigland <teigland@redhat.com> Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>

[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.
