Subject: [RFC][PATCH 21/42] getting rid of 'opened' argument of ->atomic_open() - part 2
Date:   Wed, 11 Jul 2018 03:21:45 +0100
Message-Id: <20180711022206.12571-21-viro@ZenIV.linux.org.uk>
In-Reply-To: <20180711022206.12571-1-viro@ZenIV.linux.org.uk>
References: <20180711021136.GN30522@ZenIV.linux.org.uk>
 <20180711022206.12571-1-viro@ZenIV.linux.org.uk>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

From: Al Viro <viro@zeniv.linux.org.uk>

__gfs2_lookup(), gfs2_create_inode(), nfs_finish_open() and fuse_create_open()
don't need 'opened' anymore.  Get rid of that argument in those.
