Thanks for the hint: I did it (I'll spare you the listing). The
-164-kernel ist the first one where according to "rpm -qf <path>" the
module is "owned" by the kernel package. All the other instances of
xfs.ko point to a module "owned" by kmod-xfs.
So obviously I'm not using the kmod-xfs anymore (I'm relieved that the
last kernel-update worked without a clash)
Thanks again for clearing that up
Bernhard
BTW: yes. It is a x86_64-machine
