Since the first attempt at making selinux work on top of gfs2 and similar file systems [1] was met with resistance by Christoph, here is another attempt that doesn't require any additional inode operations, but also doesn't guarantee full consistency of inode security labels: in case we cannot reload an invalid label immediately, we keep using the old one.
The xattr cleanups that were part of [1] have been split off and posted separately [2]; they seem to be okay. Any thoughts?
