[PATCH] MM: SLOB is broken by recent cleanup of slab.h
Recent cleanup of slab.h broke SLOB allocator: the routine kmem_cache_init
has now the __init attribute for both slab.c and slob.c. This routine
cannot be removed after init in the case of slob.c -- it serves as a timer
callback.
Provide a separate timer callback routine, call it once from kmem_cache_init,
keep the __init attribute on the latter.
