That version was an older take. The latest changeset is under
patches/kprobes-use-rcu/. Also note that the kprobes patches are
normally diffed against the mainline and not the FC kernels. In most
directories under patches/, a README in the directory tells which
kernel/mm the diff is against.

Another note - the patches under kprobes-use-rcu are for testing
purposes only. There probably are cases that are not covered, wrt rcu
changes. Appreciate more tests to weed out any issues to make the
patches upstreamable.

Thanks,
