The patch titled
MM: SLOB is broken by recent cleanup of slab.h
has been removed from the -mm tree. Its filename was
mm-slob-is-broken-by-recent-cleanup-of-slabh.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: MM: SLOB is broken by recent cleanup of slab.h
From: Dimitri Gorokhovik <dimitri.gorokhovik@xxxxxxx>
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.
