X-Git-Tag: v2.6.18-rc2~88

[PATCH] lockdep: annotate mm/slab.c

mm/slab.c uses nested locking when dealing with 'off-slab'
caches, in that case it allocates the slab header from the
(on-slab) kmalloc caches. Teach the lock validator about
this by putting all on-slab caches into a separate class.

this patch has no effect on non-lockdep kernels.
