Subject: [PATCH net-2.6 2/7] jme: Fix unmatched tasklet_{enable|disable} pair
Date: Mon, 29 Jun 2009 04:37:30 +0800 [thread overview]
Message-ID: <20090702183223.D527B5D2D7@cooldavid.org> (raw)
Fix faulty tasklet function usage.
It's kind of silly and critical bug, hopefully it can be applied to
2.6.31.
