[PATCHv4 0/6] Support 64-bit LUNs

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

 



Hi all,

this patchset updates the SCSI stack to support full 64-bit LUNs.
The first patch is a simple fix; the next patch updates
the sequential scan logic to be compliant with SPC.
The third patch addresses a firmware issue with earlier
qla2xxx HBAs.
The next two patches update the SCSI stack and all drivers
to use 64-bit LUNs where appropriate.
And finally we need to update the conversion routines
scsilun_to_int to cope with 64bit LUNs.

Two drivers have issues with 64bit LUNs:
- The qla2xxx driver uses a 32-bit LUN value for TMFs.
  But as the driver uses a max_lun value from 0xFFFF
  we should be safe for the time being.
- The zfcp driver uses a 32-bit LUN for debug records; the
  record format would need to be updated to cope with
  64-bit LUNs. But again, this driver uses 0xFFFFFFFF
  for max_lun, so it doesn't do any harm.

The other changes have been pretty straightforward.

Changes to v3:
- Modified scsilun_to_int() as suggested by James B.

Changes to v2:
- Add patch to fixup scsilun_to_int
- Add Reviewed-by: where applicable
- Remove last references to SCSI_MULTI_LUN

Hannes Reinecke (6):
  scsi: Remove CONFIG_SCSI_MULTI_LUN
  scsi_scan: Restrict sequential scan to 256 LUNs
  qla2xxx: Restrict max_lun to 16-bit for older HBAs
  scsi: use 64-bit LUNs
  scsi: use 64-bit value for 'max_luns'
  scsi_scan: Fixup scsilun_to_int()
