Subject: [PATCH AUTOSEL 5.4 31/37] nvme: add NVME_REQ_CANCELLED flag in nvme_cancel_request()
Date: Tue, 16 Mar 2021 20:57:56 -0400 [thread overview]
Message-ID: <20210317005802.725825-31-sashal@kernel.org> (raw)
In-Reply-To: <20210317005802.725825-1-sashal@kernel.org>
From: Hannes Reinecke <hare@suse.de>
[ Upstream commit d3589381987ec879b03f8ce3039df57e87f05901 ]
NVME_REQ_CANCELLED is translated into -EINTR in nvme_submit_sync_cmd(),
so we should be setting this flags during nvme_cancel_request() to
ensure that the callers to nvme_submit_sync_cmd() will get the correct
error code when the controller is reset.
