Subject: [PATCH pnfs-submit-wave3 update 4/5] wave3: clean up lseg after pg_doio function
Date: Tue, 1 Mar 2011 14:25:33 -0500 [thread overview]
Message-ID: <1299007534-4105-5-git-send-email-andros@netapp.com> (raw)
In-Reply-To: <1299007534-4105-4-git-send-email-andros@netapp.com>
From: Fred Isaman <iisaman@netapp.com>
nfs_pageio_doio can be repeatedly triggered, in which case
it is possible for an lseg which has already been put to be
used and put again without matching gets.
