Subject: [RFC][PATCH 20/42] getting rid of 'opened' argument of ->atomic_open() - step 1
Date: Wed, 11 Jul 2018 03:21:44 +0100	[thread overview]
Message-ID: <20180711022206.12571-20-viro@ZenIV.linux.org.uk> (raw)
In-Reply-To: <20180711022206.12571-1-viro@ZenIV.linux.org.uk>

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

'opened' argument of finish_open() is unused.  Kill it.
