autodetect: allow whitelisting by MODULE_FS_ALIAS
Linux 3.9 adds a filesystem alias in the supporting module in the form of fs-$filesystem. While this is mainly aimed at security/paranoia, it does mean that we can make better use of the fact that we always resolve filesystem as aliases to filesystem modules. Do an additional lookup in add_if_avail to resolve the new alias in addition to the filesystem name itself. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
