Subject: [RFC PATCH 06/15] vfs: make init-file static
Date: Fri, 04 Dec 2009 15:47:28 -0500	[thread overview]
Message-ID: <20091204204728.18286.75601.stgit@paris.rdu.redhat.com> (raw)
In-Reply-To: <20091204204646.18286.24853.stgit@paris.rdu.redhat.com>

init-file is no longer used by anything except alloc_file.  Make it static and
remove from headers.
