Subject: [PATCH v4 bpf-next 0/3] BPF test_progs tests improvement
Date: Tue, 8 Mar 2022 12:04:46 -0800	[thread overview]
Message-ID: <20220308200449.1757478-1-mykolal@fb.com> (raw)

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.

Mykola Lysenko (3):
  Improve perf related BPF tests (sample_freq issue)
  Improve send_signal BPF test stability
  Improve stability of find_vma BPF test
