Look at the ugly conditional locking gfs2_permission() does, which is probably due to the fact that it's doing a recursion via calling permission() from inside already locked parts in the filesystem. That's _much_ worse than a duplicated IS_IMMUTABLE() call. Which btw, is a filesystem implementation detail: it needs to re-check the immutability of the file after it has been locked. I'm not even sure it's strictly needed. Steven? Generally this sort of recursion through the VFS is ugly and unnecessary, it's much better to provide helper for what the VFS is doing if there's a lot of duplication. But in this case there's really no point in that at all.
