Subject: Re: [PATCHv4 12/14] writeback: optimize periodic bdi thread wakeups
Date: Fri, 23 Jul 2010 12:28:00 -0400 [thread overview]
Message-ID: <20100723162800.GB29633@infradead.org> (raw)
In-Reply-To: <1279897554-1526-13-git-send-email-dedekind1@gmail.com>
I haven't reviewed this in detail, but what ensures the timer is
synchronously removed when the forker goes away? I don't see a
del_timer_sync call anywhere. For now it might be easier to just
skip this patch and leave it for later.
