[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.

[DLM] Consolidate transport protocols This patch consolidates the TCP & SCTP protocols for the DLM into a single file and makes it switchable at run-time (well, at least before the DLM actually starts up!) For RHEL5 this patch requires Neil Horman's patch that expands the in-kernel socket API but that has already been twice ACKed so it should be OK. The patch adds a new lowcomms.c file that replaces the existing lowcomms-sctp.c & lowcomms-tcp.c files.

A general purpose distributed lock manager for kernel or userspace
applications.
[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.

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.
