[PATCH v2 0/4] scsi: target: COMPARE AND WRITE miscompare sense

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This patchset adds missing functionality to return the offset of
non-matching read/compare data in the sense INFORMATION field on
COMPARE AND WRITE miscompare.

The functionality can be tested using the libiscsi
CompareAndWrite.MiscompareSense test proposed via:
  https://github.com/sahlberg/libiscsi/pull/344

Changes since v2:
- perform bad_sector->sense_info rename in overlooked ib_isert
- drop scatterlist change queued via Jens' tree
- add Mike's reviewed-by tag
- rebase against Martin's 5.11/scsi-queue branch

Changes since v1:
- drop unnecessary WARN_ON()
- fix two checkpatch warnings
- drop single-use nlbas variable
- avoid compare_len recalculation

Cheers, David
