Subject: [PATCH 3/5] scsi: target: rename cmd.bad_sector to cmd.sense_info
Date: Fri, 23 Oct 2020 20:57:21 +0000	[thread overview]
Message-ID: <20201023205723.17880-4-ddiss@suse.de> (raw)
In-Reply-To: <20201023205723.17880-1-ddiss@suse.de>

cmd.bad_sector currently gets packed into the sense INFORMATION field
for TCM_LOGICAL_BLOCK_{GUARD,APP_TAG,REF_TAG}_CHECK_FAILED errors, which
carry an .add_sector_info flag in the sense_detail_table to ensure this.

In preparation for propagating a byte offset on COMPARE AND WRITE
TCM_MISCOMPARE_VERIFY error, rename cmd.bad_sector to cmd.sense_info
and sense_detail.add_sector_info to sense_detail.add_sense_info so
that it better reflects the sense INFORMATION field destination.
