Subject: [GIT PULL] SCSI fixes for 3.1-rc6
This is a set of mostly isci and qla2xxx with minor bnx2i and hpsa ones.
They've been in linux-next since before master.kernel.org was taken
offline, so they should have had lots of testing (sorry for the delay,
was hoping not to have to set up my own git server).
The head sha1 is
commit 610602f369b4c810c9df05e431abd38f38cb8e0d
The fix is available here:
git://bedivere.hansenpartnership.com/git/scsi-rc-fixes-2.6.git
The short changelog is:
Andrew Vasquez (1):
qla2xxx: Correct inadvertent loop state transitions during port-update handling.
Arun Easi (2):
qla2xxx: T10 DIF - Fix incorrect error reporting.
qla2xxx: T10 DIF - Handle uninitalized sectors.
Chad Dupuis (3):
qla2xxx: Update version number to 8.03.07.07-k.
qla2xxx: Double check for command completion if abort mailbox command fails.
qla2xxx: Fix qla24xx revision check while enabling interrupts.
Dan Williams (5):
isci: add version number
isci: fix event-get pointer increment
isci: dynamic interrupt coalescing
isci: fix 32-bit operation when CONFIG_HIGHMEM64G=n
isci: fix sata response handling
Dave Jiang (2):
isci: Adding documentation to API change and fixup sysfs registration
isci: Update MAINTAINERS entry for the isci driver
Eddie Wai (1):
bnx2i: Fixed the endian on TTT for NOP out transmission
Jeff Skirvin (1):
isci: Leave requests alone if already terminating.
Marcin Tomczak (1):
isci: change sas phy timeouts from 54us to 59us
Robert Love (1):
fcoe: Fix deadlock between fip's recv_work and rtnl
Saurav Kashyap (3):
qla2xxx: Set the task attributes after memsetting fcp cmnd.
qla2xxx: Save and restore irq in the response queue interrupt handler.
qla2xxx: Acquire hardware lock while manipulating dsd list.
Stephen M. Cameron (2):
hpsa: fix physical device lun and target numbering problem
hpsa: fix problem that OBDR devices are not detected
Vasu Dev (2):
libfc: block SCSI eh thread for blocked rports
libfc: fix fc_eh_host_reset
Yi Zou (1):
libfc: fix referencing to fc_fcp_pkt from the frame pointer via fr_fsp()

+What: /sys/class/scsi_host/hostX/isci_id
+Date: June 2011
+Contact: Dave Jiang <dave.jiang@...el.com>
+Description:
+ This file contains the enumerated host ID for the Intel
+ SCU controller. The Intel(R) C600 Series Chipset SATA/SAS
+ Storage Control Unit embeds up to two 4-port controllers in
+ a single PCI device. The controllers are enumerated in order
+ which usually means the lowest number scsi_host corresponds
+ with the first controller, but this association is not
+ guaranteed. The 'isci_id' attribute unambiguously identifies
+ the controller index: '0' for the first controller,
+ '1' for the second.
