[PATCH] fat: kill reserved names
Since these names on old MSDOS is used as device, so, current fat driver doesn't allow a user to create those names. But many OSes and even Windows can create those names actually, now. This patch removes the reserved name check. Signed-off-by: OGAWA Hirofumi <hirofumi@mail.parknet.co.jp> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
