[PATCH] fat: remove the unneeded vfat_find() in vfat_rename()
Now, vfat_rename() is using vfat_find() for sanity check. This removes that sanity check, the cost of sanity check is too high. 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>
