From: Dimitri Gorokhovik <[email protected]>
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.
