From b18fdf71e01fba29a804d63f8c1e2ed61011170d Mon Sep 17 00:00:00 2001 From: Pavel Begunkov Date: Thu, 21 Nov 2019 23:21:02 +0300 Subject: io_uring: simplify io_req_link_next() "if (nxt)" is always true, as it was checked in the while's condition. io_wq_current_is_worker() is unnecessary, as non-async callers don't pass nxt, so io_queue_async_work() will be called for them anyway.
