Subject: [patch 18/87] mm: SLUB fix reclaim_state
Date: Tue, 09 Jun 2009 02:39:06 -0700 [thread overview]
Message-ID: <20090609094056.238393901@blue.kroah.org> (raw)
In-Reply-To: <20090609094451.GA26439@kroah.com>
[-- Attachment #1: mm-slub-fix-reclaim_state.patch --]
[-- Type: text/plain, Size: 1323 bytes --]
2.6.29-stable review patch. If anyone has any objections, please let us know.
------------------
From: Nick Piggin <npiggin@suse.de>
commit 1eb5ac6466d4be7b15b38ce3ab709600f1bc891f upstream.
SLUB does not correctly account reclaim_state.reclaimed_slab, so it will
break memory reclaim. Account it like SLAB does.
