From 14c32eee9286621dd437b53460e44bd11e5bc08d Mon Sep 17 00:00:00 2001 From: Pavel Begunkov Date: Thu, 16 Jul 2020 23:28:01 +0300 Subject: [PATCH] io_uring: don't forget cflags in io_recv() Instead of returning error from io_recv(), go through generic cleanup path, because it'll retain cflags for userspace. Do the same for io_send() for consistency.
