Hi,
Thanks for the patch.

Could you wrap the changelog to 75 chars except for log (strace below) ? checkpatch.pl will help.

Every patch that fixes networking code has to be applied cleanly on net.git. https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net.git/
But the patch can not be applied to net.git. Could you check this ? https://patchwork.kernel.org/project/netdevbpf/patch/bd7ff00a-6892-fd56-b3ca-4b3feb6121d8@alu.unizg.hr/
Also, the mail title should be
[PATCH Tree Version Nth/Total] subsystem: Description.
Next time, Tree is net and Version is v2, and we need not write 1/1, so the subject should be
[PATCH net v2] af_unix: selftest: Fix size of parameter to connect()
Please see here for details. https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next.git/tree/Documentation/process/maintainer-netdev.rst

You can remove these lines.

In this case, you are the reporter and the author of the patch, so the Reported-by tag is not needed. Instead, you have to add your SOB tag.
