File system lock names are very regular right now, so we really only need to
pass an extra parameter to dlmlock().

Get rid of osb->uuid, osb->proc_sub_dir, and osb->osb_id. Those fields were
unused, or could easily be removed. As a result, we also no longer need
MAX_OSB_ID or ocfs2_globals_lock.

locking init cleanups:
- convert " = SPIN_LOCK_UNLOCKED" to spin_lock_init() or DEFINE_SPINLOCK()
- convert rwlocks in a similar manner
this patch was generated automatically.
Motivation:
- cleanliness
- lockdep needs control of lock initialization, which the open-coded
variants do not give
- it's also useful for -rt and for lock debugging in general

This is a conversion to make the various file_operations structs in fs/
const. Basically a regexp job, with a few manual fixups
The goal is both to increase correctness (harder to accidentally write to
shared datastructures) and reducing the false sharing of cachelines with
things that get dirty in .data (while .rodata is nicely read only and thus
cache clean)
