Subject: [RFC PATCH 02/15] shmem: use alloc_file instead of init_file
Date: Fri, 04 Dec 2009 15:46:56 -0500	[thread overview]
Message-ID: <20091204204656.18286.15131.stgit@paris.rdu.redhat.com> (raw)
In-Reply-To: <20091204204646.18286.24853.stgit@paris.rdu.redhat.com>

shmem uses get_empty_filp() and then init_file().  Their is no good reason
not to just use alloc_file() like everything else.
