[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.

[DLM] Fix DLM config The attached patch fixes the DLM config so that it selects the chosen network transport. It should fix the bug where DLM can be left selected when NET gets unselected. This incorporates all the comments received about this patch.

Yes, patch below. > regards, cu Adrian <-- snip --> This patch fixes a circular dependency by letting GFS2_FS_LOCKING_DLM and DLM depend on instead of select SYSFS. Since SYSFS depends on EMBEDDED this change shouldn't cause any problems for users.

[DLM] Add support for tcp communications The following patch adds a TCP based communications layer to the DLM which is compile time selectable. The existing SCTP layer gives the advantage of allowing multihoming, whereas the TCP layer has been heavily tested in previous versions of the DLM and is known to be robust and therefore can be used as a baseline for performance testing.

The DLM Can use TCP or SCTP for it's network communications.
SCTP supports multi-homed operations whereas TCP doesn't.
However, SCTP seems to have stability problems at the moment.

Under the debugfs mount point, the name of each lockspace will
appear as a file in the "dlm" directory. The output is the
list of resource and locks the local node knows about.
