Subject: [PATCH 2/7] mmc: Don't use PF_MEMALLOC
Date: Tue, 17 Nov 2009 16:17:50 +0900 (JST) [thread overview]
Message-ID: <20091117161711.3DDA.A69D9226@jp.fujitsu.com> (raw)
In-Reply-To: <20091117161551.3DD4.A69D9226@jp.fujitsu.com>
Non MM subsystem must not use PF_MEMALLOC. Memory reclaim need few
memory, anyone must not prevent it. Otherwise the system cause
mysterious hang-up and/or OOM Killer invokation.
