Subject: [PATCH 1/2] nvme: add NVME_REQ_CANCELLED flag in nvme_cancel_request()
Date: Wed, 27 Jan 2021 09:06:04 +0100	[thread overview]
Message-ID: <20210127080605.146627-2-hare@suse.de> (raw)
In-Reply-To: <20210127080605.146627-1-hare@suse.de>

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.
