vfs/fs fixes for -rc3

Contains the set that was in the previous pull request (as the matter
of fact, for-linus-2 is a couple of commits on top of for-linus). New bits:
jfs fix (yet another -PTR_ERR() bug) and Ted's sanitizing of ENOENT/EROFS on unlink() and rmdir() to match the behaviour of rename(), behaviour of the unlink()/rmdir() in old kernels *and* what POSIX asks for.
Please, pull from
git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs-2.6.git/ for-linus-2
