Subject: [PATCH v4 bpf-next 0/9] bpf: Misc improvements
Date: Tue,  9 Feb 2021 19:36:25 -0800	[thread overview]
Message-ID: <20210210033634.62081-1-alexei.starovoitov@gmail.com> (raw)

From: Alexei Starovoitov <ast@kernel.org>

v4:
- split migrate_disable into separate patch

v3:
- address review comments
- improve recursion selftest

Several bpf improvements:
- optimize prog stats
- compute stats for sleepable progs
- prevent recursion fentry/fexit and sleepable progs
- allow map-in-map and per-cpu maps in sleepable progs

Alexei Starovoitov (9):
  bpf: Optimize program stats
  bpf: Run sleepable programs with migration disabled
  bpf: Compute program stats for sleepable programs
  bpf: Add per-program recursion prevention mechanism
  selftest/bpf: Add a recursion test
  bpf: Count the number of times recursion was prevented
  selftests/bpf: Improve recursion selftest
  bpf: Allows per-cpu maps and map-in-map in sleepable programs
  selftests/bpf: Add a test for map-in-map and per-cpu maps in sleepable
    progs
