From: Keith Busch Date: Mon, 4 Jan 2016 16:10:56 +0000 (-0700) Subject: NVMe: Use a retryable error code on reset X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1d49c38c4865c596b01b31a52540275c1bb383e7;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git NVMe: Use a retryable error code on reset A negative status has the "do not retry" bit set, which makes it not retryable. Use a fake status that can potentially be retried on reset. An aborted command's status is overridden by the timeout handler so that it won't be retried, which is necessary to keep initialization from getting into a reset loop.
