Jens Axboe 361aee450c io-wq: add intermediate work step between pending list and active work ... We have a gap where a worker removes an item from the work list and to when it gets added as the workers active work. In this state, the work item cannot be found by cancelations. This is a small window, but it does exist. Add a temporary pointer to a work item that isn't on the pending work list anymore, but also not the active work. This is needed as we need to drop the wqe lock in between grabbing the work item and marking it as active, to ensure that signal based cancelations are properly ordered.
