vfs: mnt_want_write_file(): fix special file handling
I suspect that mnt_want_write_file() may have wrong assumption. I think mnt_want_write_file() is assuming it increments ->mnt_writers if (file->f_mode & FMODE_WRITE). But, if it's special_file(), it is false? Signed-off-by:OGAWA Hirofumi <hirofumi@mail.parknet.co.jp> Acked-by:
