Subject: [PATCH 2/5] NFSv4: Don't ask for the change attribute when reclaiming state
Date: Thu, 10 Nov 2016 16:41:07 -0500 [thread overview]
Message-ID: <1478814070-17140-3-git-send-email-trond.myklebust@primarydata.com> (raw)
In-Reply-To: <1478814070-17140-2-git-send-email-trond.myklebust@primarydata.com>
We don't need to ask for the change attribute when returning a delegation
or recovering from a server reboot, and it could actually cause us to
obtain an incorrect value if we're using a pNFS flavour that requires
LAYOUTCOMMIT.
