Thanks, I'll queue this for 7.3-rc1. I don't see a need to fast-track it into mainline, as 7a0cf094944e is from 2019. Can someone please send along a paragraph which describes the userspace-visible effects of the bug? I think this is important when proposing a backportable fix. Important for all fixes, really. I understand that I'm to take no action with "[PATCH v2 2/2] signal: make send_signal_locked() take const siginfo".
