Daniel Borkmann says:
====================
pull-request: bpf 2020-10-08
The main changes are:
1) Fix "unresolved symbol" build error under CONFIG_NET w/o CONFIG_INET due
to missing tcp_timewait_sock and inet_timewait_sock BTF, from Yonghong Song.
2) Fix 32 bit sub-register bounds tracking for OR case, from Daniel Borkmann.
