From d07f1e8a42614cc938c9c88866d4474a5a7fee31 Mon Sep 17 00:00:00 2001 From: Pavel Begunkov Date: Mon, 22 Mar 2021 01:45:58 +0000 Subject: [PATCH] io_uring: correct io_queue_async_work() traces Request's io-wq work is hashed in io_prep_async_link(), so as trace_io_uring_queue_async_work() looks at it should follow after prep has been done.
