Jens,

your patch doesn't compile with 5.12+. AFAIK, the reason is that
JOBCTL_TASK_WORK is gone.

Wouldn't just a call to tracehook_notify_signal from do_coredump be
enough and backward compatible with every possible stable branches?

That version is just for 5.10, the first I posted is applicable to
5.11+

Ok, in that case, I can tell you that it partially works. There is a
small thing missing.

I have tested mine which I did share in
https://lore.kernel.org/io-uring/87pmwt6biw.fsf@disp2133/T/#m3b51d44c12e39a06b82aac1d372df05312cff833 (local)

and with another small patch added to it, it does work.

I will offer my patch later today.
