Subject: Re: [RFC v2] ext4: Don't send extra barrier during fsync if there are no dirty pages.
Date: Thu, 5 Aug 2010 12:45:04 -0400 [thread overview]
Message-ID: <20100805164504.GI2901@thunk.org> (raw)
In-Reply-To: <20100805164008.GH2901@thunk.org>
P.S. If it wasn't clear, I'm still in favor of trying to coordinate
barriers across the whole file system, since that is much more likely
to help use cases that arise in real life.
