5e2fb91792 explain the hidden scsi_wait_scan Kconfig variable
People keep sending patches to expose CONFIG_SCSI_WAIT_SCAN as a tunable
item.  These patches aren't accepted upstream, so let's stop the ongoing
irritation of people due to the unconditionally installed module and its
Kconfig symbol.

a3ec723a94 [SCSI] Update wording of CONFIG_SCSI_MULTI_LUN help
I had to set CONFIG_SCSI_MULTI_LUN to y in order to get my SE W595
working when plugging it as a mass storage. Looking at SCSI option to
get a phone behaving correctly was convoluted to say the least. There
are quite a few other reports about USB card readers needing this option
as well. This patch improves the help text to make the use of the option
more obvious.

5ef074161b [SCSI] Improve SCSI_LOGGING Kconfig entry
The Kconfig entry for SCSI_LOGGING refers the reader to
drivers/scsi/scsi.c, but I didn't find any useful information
there. There is certainly logging code in that file, but the
logging types and logging levels are described in
drivers/scsi/scsi_logging.h.

Also, the procfs file referred to in the section is incorrect.
It should be /proc/sys/dev/scsi/logging_level and not
/proc/scsi/scsi.

42e9a92fe6 [SCSI] libfc: A modular Fibre Channel library
libFC is composed of 4 blocks supported by an exchange manager
and a framing library. The upper 4 layers are fc_lport, fc_disc,
fc_rport and fc_fcp. A LLD that uses libfc could choose to
either use libfc's block, or using the transport template
defined in libfc.h, override one or more blocks with its own
implementation.

The EM (Exchange Manager) manages exhcanges/sequences for all
commands- ELS, CT and FCP.

The framing library frames ELS and CT commands.

The fc_lport block manages the library's representation of the
host's FC enabled ports.

The fc_disc block manages discovery of targets as well as
handling changes that occur in the FC fabric (via. RSCN events).

The fc_rport block manages the library's representation of other
entities in the FC fabric. Currently the library uses this block
for targets, its peer when in point-to-point mode and the
directory server, but can be extended for other entities if
needed.

The fc_fcp block interacts with the scsi-ml and handles all
I/O.

a6a8d9f87e [SCSI] scsi_dh: add infrastructure for SCSI Device Handlers
Some of the storage devices (that can be accessed through multiple paths),
do need some special handling for
	1. Activating the passive path of the storage access.
	2. Decode and handle the special sense codes returned by the devices.
	3. Handle the I/Os being sent to the passive path, especially
           during the device probe time.
when accessed through multiple paths.

As of today this special device handling is done at the dm-multipath
layer using dm-handlers. That works well for (1); for (2) to be handled
at dm layer, scsi sense information need to be exported from SCSI to dm-layer,
which is not very attractive; (3) cannot be done at all at the dm layer.

Device handler has been moved to SCSI mainly to handle (2) and (3) properly.

as well.

You can flash the various blinky lights by echoing to the fault and locate files.

>From the device's point of view, you can see it has an enclosure like this:

sparkweed:~# ls /sys/class/scsi_disk/0\:0\:0\:0/device/
block:sda                     generic        queue_depth          state

delete                        ioerr_cnt      rev                  type
device_blocked                iorequest_cnt  scsi_device:0:0:0:0  uevent
driver                        modalias       scsi_disk:0:0:0:0    vendor
enclosure_component:SLOT 001  model          scsi_generic:sg0
evt_media_change              power          scsi_level

Note the enclosure_component:SLOT 001 which shows where in the enclosure
this device fits.

The astute will notice that I'm using SCSI VPD Inquiries to identify the
devices.  This, unfortunately, won't work for SATA devices unless we do
some really nasty hacking about on the SAT because the only think that
knows the SAS addresses for SATA devices is libsas, not libata where the
SAT resides.

2adbfa333a [SCSI] sgiwd93: use cached memory access to make driver work on IP28
SGI IP28 machines would need special treatment (enable adding addtional
wait states) when accessing memory uncached. To avoid this pain I
changed the driver to use only cached access to memory.
