The merge failed because this patch depends on

	[PATCH] bpf: task_group_seq_get_next: cleanup the usage of next_thread()

in this thread. But please forget.

I've sent the new series. It would be nice if you can test at least 1-5,
the last 6/6 depends on

	[PATCH 1/2] introduce __next_thread(), fix next_tid() vs exec() race
	https://lore.kernel.org/all/20230824143142.GA31222@redhat.com/

which was not merged yet.

Oleg.
