Subject: [PATCH 13/24] scsi: Kill DRIVER_SENSE
Date: Thu, 31 Oct 2019 12:04:41 +0100	[thread overview]
Message-ID: <20191031110452.73463-14-hare@suse.de> (raw)
In-Reply-To: <20191031110452.73463-1-hare@suse.de>

Replace the check for DRIVER_SENSE with a check for
SAM_STAT_CHECK_CONDITION and audit all callsites to
ensure the SAM status is set correctly.
For backwards compability move the DRIVER_SENSE definition
to sg.h, and update the sg driver to set the DRIVER_SENSE
driver_status whenever SAM_STAT_CHECK_CONDITION is present.
