Description of problem:
It would be very useful if the Fedora xen kernels worked with kprobes.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Download devel xen kernel
2. Verify kprobes not configured
kprobes is on in our current rawhide kernel-xen config. But systemtap is broken
in other ways (it fails to compile the stap scripts due to a #warning in
<linux/config.h>). It's apparently fixed in upstream systemtap CVS, so when the
fix propagates to rawhide I'll be able to test if it's actually working.
I got a direct kprobes test case from fche; all works fine on a Xen domU.
