-From: Miklos Szeredi <mszeredi@suse.cz>
-Subject: Fix use of uninitialized variable in cache_grow()
-Patch-mainline: no
-References: bnc#444597
-
-This fixes a bug in SoN-08-reserve-slub.patch.
-
-If cache_grow() was called with objp != NULL then the 'reserve' local
-variable wasn't initialized. This resulted in ac->reserve being set to
-a rubbish value.  Due to this in some circumstances huge amounts of
-slab pages were allocated (due to slab_force_alloc() returning true),
-which caused atomic page allocation failures and slowdown of the
-system.
