883d4cae4a ocfs2: allocation hints
Record the most recently used allocation group on the allocation context, so
that subsequent allocations can attempt to optimize for contiguousness.
Local alloc especially should benefit from this as the current chain search
tends to let it spew across the disk.

101ebf256d ocfs2: limit cluster bitmap information saved at mount
We were storing cluster count on the ocfs2_super structure, but never
actually using it so remove that. Also, we don't want to populate the
uptodate cache with the unlocked block read - it is technically safe as is,
but we should change it for correctness.

34af946a22 [PATCH] spin/rwlock init cleanups
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
