Subject: [PATCH 1/2] AFFS: clean up dirty flag usage
Date: Fri, 11 Jun 2010 18:05:19 +0300 [thread overview]
Message-ID: <1276268720-7398-2-git-send-email-dedekind1@gmail.com> (raw)
In-Reply-To: <1276268720-7398-1-git-send-email-dedekind1@gmail.com>
From: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
In 'affs_write_super()': remove ancient and wrong commented code,
remove unneeded 'clean' variable, so the function becomes a bit
cleaner and simpler.
In 'affs_remount(): remove unnecessary SB dirty flag changes.
