[PATCH v2 0/2] Inode security label invalidation

[Andreas Gruenbacher]

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?

Thanks,
Andreas
