c3d8336855 [SCSI] Blacklist entry for HP dat changer
after upgrading our SUN E250 from 2.4 to 2.6 I'm seeing following error
when the HP DDS4 DAT changer gets probed:

scsi: host 1 channel 0 id 5 lun16777216 has a LUN larger than allowed by
the host adapter

The device is connected to a symbios 875 host. I've talked to Willy
about the problem, and he asked me to try to blacklist the device
for reportlun. I did that with the patch below and it solved the
problem. It now gets properly detected:

f2536cbd12 [SCSI] scsi: Add IBM 2104-DU3 to blist
Some versions of the IBM 2104-DU3 disk enclosure
have been observed to hang Inquiries to non zero
LUNs to the SES device. This device only has LUN 0,
so this patch adds it to the BLIST to prevent scsi
core from scanning beyond LUN 0.

4d7db04a7a [SCSI] add SCSI_UNKNOWN and LUN transfer limit restrictions
Original From: Ingo Flaschberger <if@xip.at>

To support the RA4100 array from Compaq.

This patch now correctly handles SCSI_UNKNOWN types with regard to
BLIST_REPORTLUNS2 (allow it) and cdb[1] LUN inclusion (don't).

It also allows a BLIST_MAX_512 flag to restrict the maximum transfer
length to 512 blocks (apparently this is an RA4100 problem).

This device spews total rubbish to a REPORT LUNS command, so avoid
sending it one.

1c5363153d [SCSI] blacklist REPORT LUNS usage on transtec arrays
They report being SCSI-3 but seem to give back rubbish to a
REPORT_LUNS command.  Force them to be sequentially scanned.

Three years later...

It looks like SGI use the same FC vendor and they already have a
workaround for this issue. The following patch adds the IBM version of
it.

507caac75e [SCSI] Make the HSG80 a REPORTLUN2 device
From: 	Steve Wilcox <spwilcox@att.com>

In order to properly report LUN's > 7, the DEC HSG80 definition in
scsi_devinfo.c needs to include BLIST_REPORTLUN2 rather than
BLIST_SPARSELUN.  I've tested this change with several HSG firmware
revisions and with both Emulex and Qlogic HBA's.

0d7323c865 [SCSI] blacklist addition.
When run on a kernel that scans all LUNs, a certain crappy
scsi scanner reports the same LUN over and over..
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=155457

Aparently they were so shamed by this, they chose to remain
anonymous. Though it seems the blacklist code handles
anonymous vendors just fine.

Linus Torvalds
1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
