[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] 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.

fs: dlm: make connection hash lockless There are some problems with the connections_lock. During my experiements I saw sometimes circular dependencies with sock_lock. The reason here might be code parts which runs nodeid2con() before or after sock_lock is acquired. Another issue are missing locks in for_conn() iteration. Maybe this works fine because for_conn() is running in a context where connection_hash cannot be manipulated by others anymore. However this patch changes the connection_hash to be protected by sleepable rcu. The hotpath function __find_con() is implemented lockless as it is only a reader of connection_hash and this hopefully fixes the circular locking dependencies. The iteration for_conn() will still call some sleepable functionality, that's why we use sleepable rcu in this case. This patch removes the kmemcache functionality as I think I need to make some free() functionality via call_rcu(). However allocation time isn't here an issue. The dlm_allow_con will not be protected by a lock anymore as I think it's enough to just set and flush workqueues afterwards.

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.
