The qla2xxx driver uses ha->mbx_cmd_flags variable to pass information between
its ISR and mailbox routines, however, it does so without the protection of
any locks. Under certain conditions, this can lead to multiple mailbox

Hello Linus,
Here are remaining target-pending items for v3.9-rc7 code.
Please go ahead and pull from:
git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending.git master
The tcm_vhost patches are more than I'd usually include in a -rc7 PULL,
but are changes required for v3.9 to work

This is a set of ten bug fixes (and two consisting of copyright year
update and version number change) pretty much all of which involve
either a crash or a hang except the removal of the random sleep from the

Our testing of this patch has not shown any issues however I think we
would be more comfortable with this change if there was a callback back
into the LLDs that want to be notified of the rport state change so we
can sync up our internal fibre channel port structures. AFAICT the

Adds support for a new VIOS feature that allows ibmvfc to
optimize terminate_rport_io by telling the VIOS the target
is no longer accessible on the fabric and that it should
not send an ABTS out on the fabric to the device.

If attempting to abort requests due to a fail fail timeout
or error handling while the link is down, we cannot send
an abort out on the fabric. We can, however, send a cancel
to the VIOS. This fixes ibmvfc to send a cancel in this
case to prevent error handling from failing and/or
escalating.

Adds support for receiving FAST_IO_FAIL from fc_block_scsi_eh
when in error recovery. This fixes cases of devices being
taken offline when they are no longer accessible on the fabric,
preventing them from coming back online when the fabric recovers.

The flags on a cancel operation are intended to indicate what,
if any, TMF will follow the cancel request. This fixes a case
where we were incorrectly setting the abort task set flag on
the cancel flag when we were cancelling an abort task set.
