From d6fd77720770066a8415e6d4b390643374eedcf4 Mon Sep 17 00:00:00 2001 From: Pavel Begunkov Date: Thu, 14 Nov 2019 00:11:01 +0300 Subject: [PATCH 1018/2944] io_uring: Fix getting file for non-fd opcodes to #26323578 commit a320e9fa1e2680116d165b9369dfa41d7cc1e1d1 upstream. For timeout requests and bunch of others io_uring tries to grab a file with specified fd, which is usually stdin/fd=0.
