Subject: [PATCHv2 bpf-next 0/4] selftests/bpf: Add uprobe multi pid filter test

hi,
sending fix for uprobe multi pid filtering together with tests. The first
version included tests for standard uprobes, but as we still do not have
fix for that, sending just uprobe multi changes.

thanks,
jirka


v2 changes:
  - focused on uprobe multi only, removed perf event uprobe specific parts
  - added fix and test for CLONE_VM process filter
