5911e963d3 [SCSI] libsas: remove expander from dev list on error
If expander discovery fails (sas_discover_expander()), remove the
expander from the port device list (sas_ex_discover_expander()),
before freeing it. Else the list is corrupted and, e.g., when we
attempt to send SMP commands to other devices, the kernel oopses.

aea71a0249 [SCSI] bnx2fc: Introduce interface structure for each vlan interface
Currently, bnx2fc has a hba structure that can work with only a single vlan
interface.  When there is a change in vlan id, it does not have the capability
to switch to different vlan interface. To solve this problem, a new structure
called 'interface' has been introduced, and each hba can now have multiple
interfaces, one per vlan id.

Most of the patch is a moving the interface specific fields from hba to the
interface structure, and appropriately modifying the dereferences. A list of
interfaces (if_list) is maintained along with adapter list. During a create
call, the interface structure is allocated and added to if_list and deleted &
freed on a destroy call.  Link events are propagated to all interfaces
belonging to the hba.

573e591353 [SCSI] scsi_lib: pause between error retries
During cable pull tests on our 16G FC adapter, we are seeing errors,
typically reads to close targets, which fail due to CRC or framing
errors caused by the cable being pull (return status DID_ERROR).
The adapter detects the error on one of the first frames received,
marks the FC exchange as dead (further frames go to bit bucket) and
signals the host of the error. This action is so quick, and coupled
with fast host CPUs, creates a scenario in which the midlayer sees
the failure and retries the io almost immediately. We've seen link
traces with the retry on the link while the original i/o is still
being processed by the target. We're also seeing the time window
for the "link to pull-apart" and the physical interface to report
disconnected to be in the few millisecond range. Which means, we're
encountering scenarios where the full retry count is exhausted
(all with error) by the midlayer before the link disconnect state
is detected.

We looked at 8G FC behavior and occasionally see the same behavior,
but as the link was slower, it rarely could exhaust all retries
before the link reported disconnect.

What is needed is a slight delay between io retries due to DID_ERROR
to cover this error.  It is inappropriate to put this delay in the
driver, as the error is indistinguishable from other link-related errors,
nor does the driver track whether the io is a retry or not. This is also
easier than tracking between-io-error bursts that are seen in this
scenario.

The patch below updates the retry path so that it inserts a delay as
if the target was busy.  The busy delay is on the order of 6ms. This
delay is sufficient to ensure the link down condition is reported
before the retry count is exhausted (at most 1 retry is seen).

 - arch/xtensa/include/asm/uaccess.h
that were just easier to fix up in the merge than in the patch series.
