tgt: removal

2014-07-17T20:07:44+00:00

Now that the ibmvstgt driver as the only user of scsi_tgt is gone, the
scsi_tgt kernel module, the CONFIG_SCSI_TGT, CONFIG_SCSI_SRP_TGT_ATTRS and
CONFIG_SCSI_FC_TGT_ATTRS kbuild variable, the scsi_host_template
transfer_response method are no longer needed.

[SCSI] aci7xxx_old: delete decade+ obsolete driver

2013-12-19T15:39:02+00:00

After getting warnings in an allyesconfig build[1] from this
driver, I decided to remind myself just how old it was, and
whether it warranted fixing.  In the Kconfig help text, I found:

  "This driver will eventually be phased out entirely"

Going back to the history archive, I see the line was added[2]
in Feb 2002, when we moved from v2.4.2.1 ---> v2.4.2.2

So, with over a decade of notification, and multiple major releases
since then, I think we can justify removing this.  Currently we have
people wasting time building it during routine testing, and then
wasting more time re-researching the known reported warnings, only to
find that nobody really is willing to integrate the fixes[3] for it.

A quick search didn't seem to indicate any active user base for it.
If someone happens to have a quirky _old_ card that the eleven year
old "new" driver doesn't work with, then it is entirely reasonable
that they stick with a kernel version that predates this removal.

[SCSI] mpt3sas: add new driver supporting 12GB SAS

2012-12-01T10:09:17+00:00

These driver files are initially, substantially similar to mpt2sas but,
because mpt2sas is going into maintenance mode and mp3sas will become heavily
developed, we elected to keep the code bases separate.

[SCSI] Remove scsi_wait_scan module

2012-07-20T07:58:13+00:00

scsi_wait_scan was introduced with asynchronous host scanning as a hack
for distributions that weren't using proper udev based wait for root to
appear in their initramfs scripts.  In 2.6.30 Commit

Author: Rafael J. Wysocki 
Date:   Sun Apr 12 20:06:56 2009 +0200

    PM/Hibernate: Wait for SCSI devices scan to complete during resume

Actually broke scsi_wait_scan because it renders
scsi_complete_async_scans() a nop for modular SCSI if you include
scsi_scans.h (which this module does).

The lack of bug reports is sufficient proof that this module is no
longer used.

scsi: delete the MCA specific drivers and driver code

2012-05-17T23:03:54+00:00

The support for CONFIG_MCA is being removed, since the 20
year old hardware simply isn't capable of meeting today's
software demands on CPU and memory resources.

This commit removes the MCA specific SCSI drivers, and the
MCA specific portions of code in dual role ISA/MCA drivers.
Also, the MCA specific SCSI documentation is removed.

Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi-misc-2.6

Pull SCSI updates from James Bottomley:
 "This is primarily another round of driver updates (lpfc, bfa, fcoe,
  ipr) plus a new ufshcd driver.  There shouldn't be anything
  controversial in here (The final deletion of scsi proc_ops which
  caused some build breakage has been held over until the next merge
  window to give us more time to stabilise it).

  I'm afraid, with me moving continents at exactly the wrong time,
  anything submitted after the merge window opened has been held over to
  the next merge window."
