Subject: [PATCH 8/8] vfs - remove unused have_submounts() function
Date: Tue, 11 Oct 2016 13:34:28 +0800 [thread overview]
Message-ID: <20161011053428.27645.12310.stgit@pluto.themaw.net> (raw)
In-Reply-To: <20161011053352.27645.83962.stgit@pluto.themaw.net>
Now that path_has_submounts() has been added have_submounts() is no
longer used so remove it.
