Merge branch 'BPF test_progs tests improvement'
Mykola Lysenko says:
====================
First patch reduces the sample_freq to 1000 to ensure test will
work even when kernel.perf_event_max_sample_rate was reduced to 1000.
Patches for send_signal and find_vma tune the test implementation to
make sure needed thread is scheduled. Also, both tests will finish as
soon as possible after the test condition is met.
====================
