Subject: [PATCHv3 0/6] Support 64-bit LUNs
Date: Sat, 31 May 2014 11:01:12 +0200 [thread overview]
Message-ID: <1401526878-119472-1-git-send-email-hare@suse.de> (raw)
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 routine
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.
Changed 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()
