[PATCH bpf-next 0/2] Fix test_probe_user on s390x

[Ilya Leoshkevich <iii@xxxxxxxxxxxxx>]

Hi,

This is a fix for [1]: test_probe_user fails on s390x, because it hooks
only connect(), but not socketcall(SYS_CONNECT).

Patch 1 adds this quirk to BPF_KSYSCALL documentation.
Patch 2 fixes the test by attaching a prog to socketcall().

Best regards,
Ilya
