3881ac04eb 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.

52bda2b5ba 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.

e7fd41792f [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.
