Subject: [PATCH 03/26] pNFS: Clear NFS_LAYOUT_RETURN_REQUESTED when invalidating the layout stateid
Date: Thu, 1 Dec 2016 17:18:59 -0500 [thread overview]
Message-ID: <20161201221922.15657-4-trond.myklebust@primarydata.com> (raw)
In-Reply-To: <20161201221922.15657-3-trond.myklebust@primarydata.com>
We must ensure that we don't schedule a layoutreturn if the layout stateid
has been marked as invalid.
Fixes: 2a59a0411671e ("pNFS: Fix pnfs_set_layout_stateid() to clear...")
