Subject: [RFC PATCH 1/6] shmem: use alloc_file instead of init_file
Date: Thu, 03 Dec 2009 14:58:51 -0500	[thread overview]
Message-ID: <20091203195851.8925.30926.stgit@paris.rdu.redhat.com> (raw)

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