Just in case, I obviously meant our next (V2) patch

[PATCH v2 2/2] kernel: rerun task_work while freezing in get_signal()
https://lore.kernel.org/all/149ff5a762997c723880751e8a4019907a0b6457.1720534425.git.asml.silence@xxxxxxxxx/

Than I think we can forget about task_works and this patch. CRIU dumps
the tasks in TASK_TRACED state.
