Subject: [PATCH v4 for-6.0 10/12] esp: don't reset async_len directly in esp_select() if cancelling request
Date: Wed,  7 Apr 2021 20:57:59 +0100	[thread overview]
Message-ID: <20210407195801.685-11-mark.cave-ayland@ilande.co.uk> (raw)
In-Reply-To: <20210407195801.685-1-mark.cave-ayland@ilande.co.uk>

Instead let the SCSI layer invoke the .cancel callback itself to cancel and
reset the request state.
