From 06bdea20c1076471f7ab7d3ad7f35cbcbd59a8e3 Mon Sep 17 00:00:00 2001 From: Pavel Begunkov Date: Tue, 23 Nov 2021 00:07:46 +0000 Subject: [PATCH] io_uring: simplify reissue in kiocb_done Simplify failed resubmission prep in kiocb_done(), it's a bit ugly with conditional logic and hand handling cflags / select buffers. Instead, punt to tw and use io_req_task_complete() already handling all the cases.
