Subject: [PATCH 11/12] fs: allow to mount on subdirectories
Date: Wed, 15 Feb 2012 09:22:44 +0100 [thread overview]
Message-ID: <1329294165-12089-12-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1329294165-12089-1-git-send-email-s.hauer@pengutronix.de>
Since get_mtab_entry_by_path() is a bit more flexible now
we no longer have to force the user to mount on the root
directory only. Instead, we can allow to mount on subdirectories
aswell. Nested mounts are still not possible though.
