Subject: [PATCH RFC] memcg: fix drain_all_stock crash
Date: Tue, 9 Aug 2011 11:31:50 +0200 [thread overview]
Message-ID: <20110809093150.GC7463@tiehlicka.suse.cz> (raw)
In-Reply-To: <20110809072615.GA7463@tiehlicka.suse.cz>
What do you think about the half backed patch bellow? I didn't manage to
test it yet but I guess it should help. I hate asymmetry of drain_lock
locking (it is acquired somewhere else than it is released which is
not). I will think about a nicer way how to do it.
Maybe I should also split the rcu part in a separate patch.
What do you think?
