Subject: [PATCH v2 0/4] scsi: 64-bit LUN support
Date: Wed, 20 Feb 2013 14:47:10 +0100 [thread overview]
Message-ID: <1361368034-54444-1-git-send-email-hare@suse.de> (raw)
This patchset updates the SCSI midlayer to use 64-bit LUNs internally.
It eliminates the need to limit the number of LUNs artificially to
avoid aliasing issues; the SCSI midlayer can now accept any LUN presented
to it.
The LLDD specific settings for 'max_lun' have been left untouched;
it should be raised to '~0' if the HBA supports 64-bit LUNs internally.
However, it is up to the driver maintainer to raise that limit.
Changes to v1:
- Use u64 instead of uint64_t where appropriate
Hannes Reinecke (4):
scsi_scan: Fixup scsilun_to_int()
scsi: use 64-bit LUNs
scsi: use 64-bit value for 'max_luns'
scsi: Remove CONFIG_SCSI_MULTI_LUN
