Re: [PATCH] fork: fix copy_process(CLONE_PARENT) race with the exiting ->real_parent

But it does look like a real data race, and the fix looks small and obvious enough that I think it's stable material.

Agreed, the patch looks fine for -stable. I don't think that cgroup_can_fork() could ever use thread_group_leader() or anything else which checks ->exit_code...

And I see that Greg has already sent the patches with the correct modifications for the case when we need "clone_flags & CSIGNAL" rather than args->exit_signal.

Thanks Greg,

Oleg.
