How it is now:
[root@ssdandy acme]# perf probe --del *:*
Removed event: probe:icmp_rcv
[root@ssdandy acme]# perf probe --del *:*
Removed event: probe_ex:main
[root@ssdandy acme]# perf probe --del *:*
Info: Event "*:*" does not exist.
Error: Failed to delete events.
[root@ssdandy
I.e. it'll first remove all kprobes, then bail out, next time we ask for
everything to be deleted, there are no kprobes, so it will try the
uprobes, removing it all, I think it should not be a two step process
:-)

Yes, this should clear all events if user gives "*:*".
Thank you for reporting! :)
