Untested, and I'll recheck this patch tomorrow, perhaps I missed something... Mateusz, this patch has minor conflicts with your [PATCH v3 0/6] reduce tasklist_lock hold time on exit and do some WIP changes. I can wait for v4 from you and rebase on top, but I'd like to show this patch right now to simplify the review. Oleg.
