From 2817df3ae9d70900eae9e3a7f399ab5ec5524728 Mon Sep 17 00:00:00 2001 From: Naohiro Aota Date: Tue, 22 Aug 2023 16:28:50 +0900 Subject: [PATCH] aio-dio-write-verify: check for the IO errors The async write IOs can return some errors, which may lead to a short read or corruption in io_verify() stage. Catch an error early to identify the root cause easily.
