From bcb4ddb46a4c66d64d091e7ffa951b2aa1ba537f Mon Sep 17 00:00:00 2001 From: Dimitri Gorokhovik Date: Fri, 29 Dec 2006 16:48:28 -0800 Subject: [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.
