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

Pull final round of SCSI updates from James Bottomley:
 "This is primarily another round of driver updates (bnx2fc, qla2xxx,
  qla4xxx) including the target mode driver for qla2xxx.  We've also got
  a couple of regression fixes (async scanning, broken this merge window
  and a fix to a long standing break in the scsi_wait_scan module)."

* tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (45 commits)
  [SCSI] fix scsi_wait_scan
  [SCSI] fix async probe regression
  [SCSI] be2iscsi: fix dma free size mismatch regression
  [SCSI] qla4xxx: Update driver version to 5.02.00-k17
  [SCSI] qla4xxx: Capture minidump for ISP82XX on firmware failure
  [SCSI] qla4xxx: Add change_queue_depth API support
  [SCSI] qla4xxx: Fix clear ddb mbx command failure issue.
  [SCSI] qla4xxx: Fix kernel panic during discovery logout.
  [SCSI] qla4xxx: Correct early completion of pending mbox.
  [SCSI] fcoe, bnx2fc, libfcoe: SW FCoE and bnx2fc use FCoE Syfs
  [SCSI] libfcoe: Add fcoe_sysfs
  [SCSI] bnx2fc: Allocate fcoe_ctlr with bnx2fc_interface, not as a member
  [SCSI] fcoe: Allocate fcoe_ctlr with fcoe_interface, not as a member
  [SCSI] Fix dm-multipath starvation when scsi host is busy
  [SCSI] ufs: fix potential NULL pointer dereferencing error in ufshcd_prove.
  [SCSI] qla2xxx: don't free pool that wasn't allocated
  [SCSI] mptfusion: unlock on error in mpt_config()
  [SCSI] tcm_qla2xxx: Add >= 24xx series fabric module for target-core
  [SCSI] qla2xxx: Add LLD target-mode infrastructure for >= 24xx series
  [SCSI] Revert "qla2xxx: During loopdown perform Diagnostic loopback."

What: /sys/bus/fcoe/ctlr_X
Date: March 2012
KernelVersion: TBD
Contact: Robert Love <robert.w.love@intel.com>, devel@open-fcoe.org
Description: 'FCoE Controller' instances on the fcoe bus
Attributes:
fcf_dev_loss_tmo: Device loss timeout peroid (see below). Changing
this value will change the dev_loss_tmo for all
FCFs discovered by this controller.
lesb_link_fail: Link Error Status Block (LESB) link failure count.
lesb_vlink_fail: Link Error Status Block (LESB) virtual link
failure count.
lesb_miss_fka: Link Error Status Block (LESB) missed FCoE
Initialization Protocol (FIP) Keep-Alives (FKA).
lesb_symb_err: Link Error Status Block (LESB) symbolic error count.
lesb_err_block: Link Error Status Block (LESB) block error count.
lesb_fcs_error: Link Error Status Block (LESB) Fibre Channel
Serivces error count.
Notes: ctlr_X (global increment starting at 0)
What: /sys/bus/fcoe/fcf_X
Date: March 2012
KernelVersion: TBD
Contact: Robert Love <robert.w.love@intel.com>, devel@open-fcoe.org
Description: 'FCoE FCF' instances on the fcoe bus. A FCF is a Fibre Channel
Forwarder, which is a FCoE switch that can accept FCoE
(Ethernet) packets, unpack them, and forward the embedded
Fibre Channel frames into a FC fabric. It can also take
outbound FC frames and pack them in Ethernet packets to
be sent to their destination on the Ethernet segment.
Attributes:
fabric_name: Identifies the fabric that the FCF services.
switch_name: Identifies the FCF.
priority: The switch's priority amongst other FCFs on the same
fabric.
selected: 1 indicates that the switch has been selected for use;
0 indicates that the swich will not be used.
fc_map: The Fibre Channel MAP
vfid: The Virtual Fabric ID
mac: The FCF's MAC address
fka_peroid: The FIP Keep-Alive peroid
fabric_state: The internal kernel state
"Unknown" - Initialization value
"Disconnected" - No link to the FCF/fabric
"Connected" - Host is connected to the FCF
"Deleted" - FCF is being removed from the system
dev_loss_tmo: The device loss timeout peroid for this FCF.
Notes: A device loss infrastructre similar to the FC Transport's
is present in fcoe_sysfs. It is nice to have so that a
link flapping adapter doesn't continually advance the count
used to identify the discovered FCF. FCFs will exist in a
"Disconnected" state until either the timer expires and the
FCF becomes "Deleted" or the FCF is rediscovered and becomes
"Connected."
Users: The first user of this interface will be the fcoeadm application,
which is commonly packaged in the fcoe-utils package.
