Subject: [PATCH 03/11] NFSv4.1: add callback to nfs4_commit_done
Date: Wed, 23 Mar 2011 08:30:04 -0400 [thread overview]
Message-ID: <1300883412-32296-4-git-send-email-iisaman@netapp.com> (raw)
In-Reply-To: <1300883412-32296-1-git-send-email-iisaman@netapp.com>
Add a callback that the pnfs layout driver can use to do its own
error handling of the data server's COMMIT response.
