I'm not sure what the call trace is saying. User has been requested to
run xfs_repair -n to see if it's really corrupt and maybe get more
information in what manner it's corrupted. I don't think it's
selinux-policy related at all, I tried reproducing it in a ppc64le VM
and couldn't. But there's differences in the qemu commands we used
that I don't know enough about, which I note in the bug.

Thanks,

A free space tree is corrupted. What caused it is unknown, and
without a reproducer we are unlikely to be able to find it.
xfs_repair is needed to rebuild the free space trees and hence fix
the corruption.

It's not. Might be xattr related (because relabelling manipulates
xattrs), but there's really nothing to go on at this point.

Cheers,

Dave.
