[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: use dlm prefix on alloc and free functions The dlm functions in memory.c should use the dlm_ prefix. Also, use kzalloc/kfree directly for dlm_direntry's, removing the wrapper functions. Signed-off-by: David Teigland <teigland@redhat.com>

dlm: improve rsb searches By pre-allocating rsb structs before searching the hash table, they can be inserted immediately. This avoids always having to repeat the search when adding the struct to hash list. This also adds space to the rsb struct for a max resource name, so an rsb allocation can be used by any request. The constant size also allows us to finally use a slab for the rsb structs. Signed-off-by: David Teigland <teigland@redhat.com>
