Subject: Re: [PATCH 3/3] xfs: flush the CIL via a workqueue
Date: Mon, 18 Jul 2011 22:03:17 -0400 [thread overview]
Message-ID: <20110719020317.GC4259@infradead.org> (raw)

Generally looks okay, but doing a context switch in every log force
might bite us. Less the general context switch overhead, but more
the nasty interactions with cfq, which are causing huge problems
for ext3/4, with no good way to fix them for workqueues.
