iscsi_boot_sysfs does not depend on firmware. Any iscsi driver
can use it. This patch moves iscsi_boot_sysfs to the scsi
dir, so that it can be used on any arch with any driver.Signed-off-by: Mike Christie

This patch (as1397b) converts the SCSI midlayer to use the new PM
callbacks (struct dev_pm_ops). A new source file, scsi_pm.c, is
created to hold the new callback routines, and the existing
suspend/resume code is moved there.Signed-off-by: Alan Stern

Encapsulation protocol for running Fibre Channel over Ethernet interfaces.
Creates virtual Fibre Channel host adapters using libfc.This layer is the LLD to the scsi-ml. It allocates the Scsi_Host, utilizes
libfc for Fibre Channel protocol processing and interacts with netdev to
send/receive Ethernet packets.Signed-off-by: Robert Love
Signed-off-by: James Bottomley -
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.Signed-off-by: Robert Love

Support for controllers and disks that implement DIF protection
information:- During command preparation the RDPROTECT/WRPROTECT must be set
correctly if the target has DIF enabled.- READ(6) and WRITE(6) are not supported when DIF is on.
- The controller must be told how to handle the I/O via the
protection operation field in scsi_cmnd.- Refactor the I/O completion code that extracts failed LBA from the
returned sense data and handle DIF failures correctly.- sd_dif.c implements the functions required to prepare and complete
requests with protection information attached.Signed-off-by: Martin K. Petersen

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.

This adds support to SCSI for enclosure services devices. It also makes
use of the enclosure services added in an earlier patch to display the
enclosure topology in sysfs.At the moment, the enclosures are SAS specific, but if anyone actually
has a non-SAS enclosure that follows the SES-2 standard, we can add that
as well.On my Vitesse based system, the enclosures show up like this:

this device fits.The astute will notice that I'm using SCSI VPD Inquiries to identify the

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.Signed-off-by: James Bottomley
