Subject: [PATCH bpf-next 0/2] selftests/bpf: Add uprobe pid filter test

hi,
in response to [1] patch, I'm adding bpf selftest that confirms the
change fixes problem for bpf programs trigered by return uprobe created
over perf event.

Oleg pointed out other issues with uprobe_multi pid filter,
I plan to send another patchset for that.

thanks,
jirka
