      xen-scsifront: Add Xen PV SCSI frontend driver · 8beb8d4c
      由 Juergen Gross 提交于 
      Introduces the Xen pvSCSI frontend. With pvSCSI it is possible for a
Xen domU to issue SCSI commands to a SCSI LUN assigned to that
domU. The SCSI commands are passed to the pvSCSI backend in a driver
domain (usually Dom0) which is owner of the physical device. This
allows e.g. to use SCSI tape drives in a Xen domU.

The code is taken from the pvSCSI implementation in Xen done by
Fujitsu based on Linux kernel 2.6.18.

Changes from the original version are:
- port to upstream kernel
- put all code in just one source file
- move module to appropriate location in kernel tree
- adapt to Linux style guide
- some minor code simplifications
- replace constants with defines
- remove not used defines
- add support for larger SG lists by putting them in a granted page

      scsi: Use 'depends' with LIBFC instead of 'select'. · df568d8e
      由 David S. Miller 提交于 
      LIBFC depends upon SCSI_FC_ATTRS and select's CRC32C.

The only alternative would be to 'select' CRC32C and all of
SCSI_FC_ATTRS direct and indirect dependencies in the Kconfig section
for every LIBFCOE user which makes little sense.

Subsequently, use 'depends' instead of 'select' for LIBFCOE too.

      scsi: use 'depends' instead of 'select' for SCSI_FC_ATTRS · 6a38792c
      由 Randy Dunlap 提交于 
      There are other kconfig symbols which use SCSI_FC_ATTRS.
In order to maintain sanity and prevent kconfig warnings, change
all of these from using 'select' to using 'depends on' so that
proper symbol dependencies will be honored and circular depends
problems will be avoided.
This fixes kconfig warnings and build errors:

warning: (LIBFC && SCSI_IBMVFC && SCSI_QLA_FC && SCSI_LPFC && ZFCP && SCSI_BFA_FC && SCSI_CHELSIO_FCOE && FUSION_FC) selects SCSI_FC_ATTRS which has unmet direct dependencies (SCSI && NET)

      virtio-scsi: Enable DIF/DIX modes in SCSI host LLD · e6dc783a
      由 Nicholas Bellinger 提交于 
      This patch updates virtscsi_probe() to setup necessary Scsi_Host
level protection resources. (currently hardcoded to 1)

It changes virtscsi_add_cmd() to attach outgoing / incoming
protection SGLs preceeding the data payload, and is using the
new virtio_scsi_cmd_req_pi->pi_bytes[out,in] field to signal
to signal to vhost/scsi bytes to expect for protection data.

      scsi: async sd resume · 3c31b52f
      由 Dan Williams 提交于 
      async_schedule() sd resume work to allow disks and other devices to
resume in parallel.

This moves the entirety of scsi_device resume to an async context to
ensure that scsi_device_resume() remains ordered with respect to the
completion of the start/stop command.  For the duration of the resume,
new command submissions (that do not originate from the scsi-core) will
be deferred (BLKPREP_DEFER).

It adds a new ASYNC_DOMAIN_EXCLUSIVE(scsi_sd_pm_domain) as a container
of these operations.  Like scsi_sd_probe_domain it is flushed at
sd_remove() time to ensure async ops do not continue past the
end-of-life of the sdev.  The implementation explicitly refrains from
reusing scsi_sd_probe_domain directly for this purpose as it is flushed
at the end of dpm_resume(), potentially defeating some of the benefit.
Given sdevs are quiesced it is permissible for these resume operations
to bleed past the async_synchronize_full() calls made by the driver
core.

We defer the resolution of which pm callback to call until
scsi_dev_type_{suspend|resume} time and guarantee that the callback
parameter is never NULL.  With this in place the type of resume
operation is encoded in the async function identifier.

There is a concern that async resume could trigger PSU overload.  In the
enterprise, storage enclosures enforce staggered spin-up regardless of
what the kernel does making async scanning safe by default.  Outside of
that context a user can disable asynchronous scanning via a kernel
command line or CONFIG_SCSI_SCAN_ASYNC.  Honor that setting when
deciding whether to do resume asynchronously.

Inspired by Todd's analysis and initial proposal [2]:

      [SCSI] aci7xxx_old: delete decade+ obsolete driver · 1a4049dd
      由 Paul Gortmaker 提交于 
      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] lpfc: Don't force CONFIG_GENERIC_CSUM on · f5944daa
      由 Anton Blanchard 提交于 
      We want ppc64 to be able to select between optimised assembly
checksum routines in big endian and the generic lib/checksum.c
routines in little endian.

The lpfc driver is forcing CONFIG_GENERIC_CSUM on which means
we are unable to make the decision to enable it in the arch
Kconfig. If the option exists it is always forced on.

This got introduced in 3.10 via commit 6a7252fd ([SCSI] lpfc:
fix up Kconfig dependencies). I spoke to Randy about it and
the original issue was with CRC_T10DIF not being defined.

As such, remove the select of CONFIG_GENERIC_CSUM.

      [SCSI] Remove scsi_wait_scan module · 6072609d
      由 James Bottomley 提交于 
      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

    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.
