Subject: [PATCH blktests] common/fio: do not use norandommap with verify
Date: Thu, 30 Jan 2020 09:49:41 +0100	[thread overview]
Message-ID: <20200130084941.60943-1-k.jensen@samsung.com> (raw)
In-Reply-To: CGME20200130084950eucas1p2dac69024658d531d5f69ea0bdbd2be81@eucas1p2.samsung.com

As per the fio documentation, using norandommap with an async I/O engine
and I/O depth > 1, can cause verification errors.
