I'm not going through this series backwards, but I did run the kprobe
sample modules first, and nothing happened... (i.e. nothing fired).
The kernel usage of do_fork (which is used as an example by the sample
code) has been changed by:
3033f14a clone: support passing tls argument via C rather than pt_regs magic
Now everything appears to go through _do_fork rather than do_fork.
I'll send a fixup shortly, but if anyone else is running these modules
and worrying about a lack of events... worry less :-).
