Eric, Linus, et al,
by various reasons I have not been reading emails for last weeks, I'll try to read this thread tomorrow, currently I am a bit lost.

This is what I tried to do 3 years ago, see
[PATCH 1/2] exec: don't wait for zombie threads with cred_guard_mutex held https://lore.kernel.org/lkml/20170213141516.GA30233@redhat.com/
yes, yes, yes, the patch is not pretty.
From your another email:
> /* if the parent is going through a execve(), it's not listening */ > if (parent->signal->group_exit_task) return false;
Heh ;) see
[PATCH 2/2] ptrace: ensure PTRACE_EVENT_EXIT won't stop if the tracee is killed by exec https://lore.kernel.org/lkml/20170213141519.GA30239@redhat.com/
from the same thread.
But this change is more problematic.
Oleg.
