From 464a00c9e0ad45e3f42ff6ea705491a356df818e Mon Sep 17 00:00:00 2001 From: Hannes Reinecke Date: Tue, 27 Apr 2021 10:30:15 +0200 Subject: scsi: core: Kill DRIVER_SENSE Replace the check for DRIVER_SENSE with a check for scsi_status_is_check_condition(). Audit all callsites to ensure the SAM status is set correctly. For backwards compability move the DRIVER_SENSE definition to sg.h, and update sg, bsg, and scsi_ioctl to set the DRIVER_SENSE driver_status whenever SAM_STAT_CHECK_CONDITION is present.
