This is just a set of reasonably minor bug fixes ... the most serious
seems to be the BSG compat issue because BSG just doesn't work in a 32
on 64 environment at the moment.
The fix is available from:
master.kernel.org:/pub/scm/linux/kernel/git/jejb/scsi-rc-fixes-2.6.git
The short changelog is:
Anirban Chakraborty (1):
qla2xxx: Obtain proper host structure during response-queue processing.
FUJITA Tomonori (1):
compat_ioct: fix bsg SG_IO
Kashyap, Desai (1):
mptfusion : mptscsih_abort return value should be SUCCESS instead of value 0.
Swen Schillig (1):
zfcp: Report FC BSG errors in correct field
Xiaotian Feng (1):
qla2xxx: make msix interrupt handler safe for irq

James hi.
Please add this patch for 2.6.33-rc:
http://marc.info/?l=linux-scsi&m=126335810027706&w=2
Titled:
[PATCH 1/1] iscsi_tcp regression: remove bogus warn on in write path
It is a bug introduced in this Kernel. It causes an annoying useless WARN_ON
on ever iscsi login, (and scares the users ;))
Thanks
