Subject: [PATCH 3.14 24/47] nfs: if we have no valid attrs, then dont declare the attribute cache valid
Date: Wed, 20 Jan 2016 14:00:56 -0800	[thread overview]
Message-ID: <20160120215511.200757189@linuxfoundation.org> (raw)
In-Reply-To: <20160120215507.575738941@linuxfoundation.org>

3.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Jeff Layton <jlayton@poochiereds.net>

commit c812012f9ca7cf89c9e1a1cd512e6c3b5be04b85 upstream.

If we pass in an empty nfs_fattr struct to nfs_update_inode, it will
(correctly) not update any of the attributes, but it then clears the
NFS_INO_INVALID_ATTR flag, which indicates that the attributes are
up to date. Don't clear the flag if the fattr struct has no valid
attrs to apply.
