Audit will sometimes log the inode's i_uid and i_gid. Enable audit to log the
mapped inode when it is accessed from an idmapped mount.
I mentioned this in an earlier patch in this patchset, but it is worth
repeating here: audit currently records information in the context of
the initial/host namespace and I believe it should probably stay that
way until the rest of the namespace smarts that Richard is working on
is merged. If we do change the context of the inode's UID and GID
information it has the potential to create a rather odd looking audit
record with inconsistent credentials and the filters would yield some
very interesting results.
