- Fix tcp_bpf_sendmsg() error path mistaking a concurrently-freed
sk_psock->cork for the local temporary message and freeing it
again. (Chengfeng Ye)
- Reject passing scalar NULL to nonnull arg of a global subprog.
Previously the verifier did not account for the cases directly
passing scalars to a global subprog, e.g.: 'global_func(0);'
would pass even if 'global_func' argument was marked nonnull.
