Series [v3,1/4] scsi: target: rename struct sense_info to sense_detail | expand

Commit Message

David Disseldorp Oct. 30, 2020, 9:39 p.m. UTC 
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.
