io_link_timeout_fn() is the hrtimer callback that fires when a linked timeout expires. It currently calls io_remove_next_linked(prev) under ctx->timeout_lock to splice the timeout request out of the link chain. This is the only chain-mutation site that runs without ctx->uring_lock, because hrtimer callbacks cannot take a mutex. Defer the splicing until the task_work callback.
