Happy new year!
Last year the commit afd20b9290e1 ("af_unix: Replace the big lock with
small locks.") landed on bpf-next. Now we can use a batching algorithm
for bpf unix iter as bpf tcp iter.
Note that the first patch only can be a candidate for the bpf tree.
Kuniyuki Iwashima (6):
bpf: Fix SO_RCVBUF/SO_SNDBUF handling in _bpf_setsockopt().
bpf: Add SO_RCVBUF/SO_SNDBUF in _bpf_getsockopt().
bpf: af_unix: Use batching algorithm in bpf unix iter.
bpf: Support bpf_(get|set)sockopt() in bpf unix iter.
selftest/bpf: Test batching and bpf_(get|set)sockopt in bpf unix iter.
selftest/bpf: Fix a stale comment.
