Subject: [PATCH 15/19] pnfs/blocklayout: don't set pages uptodate
Date: Thu, 21 Aug 2014 11:09:31 -0500	[thread overview]
Message-ID: <1408637375-11343-16-git-send-email-hch@lst.de> (raw)
In-Reply-To: <1408637375-11343-1-git-send-email-hch@lst.de>

The core nfs code handles setting pages uptodate on reads, no need to mess
with the pageflags outselves.  Also remove a debug function to dump page
flags.
