rest is fairly minor. It was supposed to go in last round, but
various issues pushed it to this release instead. The pull request

- Various smaller blk-mq fixes from different folks. Nothing major
here, just minor fixes and cleanups.
- Fix for a memory leak in the error path in the block ioctl code
from Christian Engelmayer.
- Header export fix from CaiZhiyong.
- Finally the immutable biovec changes from Kent Overstreet. This
enables some nice future work on making arbitrarily sized bios
possible, and splitting more efficient. Related fixes to immutable

The rport timers must be stopped before the SRP initiator destroys the
resources associated with the SCSI host. This is necessary because
otherwise the callback functions invoked from the SRP transport layer
could trigger a use-after-free. Stopping the rport timers before
invoking scsi_remove_host() can trigger long delays in the SCSI error
handler if a transport layer failure occurs while scsi_remove_host()
is in progress. Hence move the code for stopping the rport timers from
srp_rport_release() into a new function and invoke that function after
scsi_remove_host() has finished. This patch fixes the following
sporadic kernel crash:

The current behavior of the SRP transport layer when a transport layer
error is encountered is to block SCSI command processing only if
fast_io_fail_tmo != off. The current behavior of the FC transport
layer when a transport layer error is encountered is to block SCSI
command processing no matter which value fast_io_fail_tmo has been set
to. Make the behavior of the SRP transport layer consistent with that
of the FC transport layer to avoid confusion.

This patch changes qla2xxx qlt_lport_register() code to accept
target_lport_ptr + npiv_wwpn + npiv_wwnn parameters, and updates
tcm_qla2xxx to use the new tcm_qla2xxx_lport_register_npiv_cb()
callback for invoking fc_vport_create() from configfs context
via tcm_qla2xxx_npiv_make_lport() code.
In order for this to work, the qlt_lport_register() callback is
now called without holding qla_tgt_mutex, as the fc_vport creation
process will call qlt_vport_create() -> qlt_add_target(), which
already expects to acquire it.
It enforces /sys/kernel/config/target/qla2xxx_npiv/$NPIV_WWPN
naming in the following format:
$PHYSICAL_WWPN@$NPIV_WWPN:$NPIV_WWNN
and assumes the $PHYSICAL_WWPN in question has already had been
configured for target mode in non NPIV mode.
Finally, it updates existing tcm_qla2xxx_lport_register_cb() logic
to setup the non NPIV assignments that have now been moved out of
qlt_lport_register() code.

This patch fixes a possible scsi_host reference leak in qlt_lport_register(),
when a non zero return from the passed (*callback) does not call drop the

This currently does not effect existing tcm_qla2xxx code as the passed callback
will never fail, but fix this up regardless for future code.

These interfaces:
pcibios_resource_to_bus(struct pci_dev *dev, *bus_region, *resource)
pcibios_bus_to_resource(struct pci_dev *dev, *resource, *bus_region)
took a pci_dev, but they really depend only on the pci_bus. And we want to
use them in resource allocation paths where we have the bus but not a
device, so this patch converts them to take the pci_bus instead of the
pci_dev:
pcibios_resource_to_bus(struct pci_bus *bus, *bus_region, *resource)
pcibios_bus_to_resource(struct pci_bus *bus, *resource, *bus_region)
In fact, with standard PCI-PCI bridges, they only depend on the host
bridge, because that's the only place address translation occurs, but
we aren't going that far yet.

This patch removes a bug in enlarge_buffer() that can make a
read or write fail under special conditions.
After changing TRY_DIRECT_IO to 0 and ST_MAX_SG to 32 in
st_options.h, a program that writes a first block of 128k and
than a second bigger block (e.g. 256k) fails. The second write
returns errno EOVERFLOW, as enlarge_buffer() checks the sg list
and detects that it already is full.
As enlarge_buffer uses different page allocation orders
depending on the size of the buffer needed, the check does not
make sense.

This patch fixes a possible scsi_host reference leak in qlt_lport_register(),
when a non zero return from the passed (*callback) does not call drop the
local reference via scsi_host_put() before returning.
This currently does not effect existing tcm_qla2xxx code as the passed callback
will never fail, but fix this up regardless for future code.

Observed Auto mode in the HBA side while doing manual D-Port test on the
switch side. Mode is not passed to BFA from firmware when the test is
triggered by switch side. BFA just blindly using Auto mode.

In direct attach mode, if port features like QoS/Trunk/FEC/CR are
enabled, driver can receive PLOGI from the target before firmware
notifies lport online to the driver. In case the lport is not yet online
and a PLOGI is received, send a reject to the peer port, instead of
dropping it on the floor.

This patch includes change to enable firmware patch simplication
feature. This feature is targeted to address the requirement to have
independent patch release for firmware. Prior to 3.2.3, releasing a
patch fix for firmware requires changes to bfa, to use new firmware
images. But with these changes, if the new firmware is flashed on to the
HBA with brocade adapter management utilites, driver uses the new
firmware after checking the patch release byte in the firmware version.

'ISCSI_NET_PARAM_VLAN_PRIORITY' and also a potential junk pointer free if
mgmt_get_if_info() returns error because if_info will be unset and it is stack

do_div() is meant for divisions of 64-bit number by 32-bit numbers.
Passing 64-bit divisor types caused issues in the past on 32-bit platforms,
cfr. commit ea077b1b96 ("m68k: Truncate base
in do_div()").
As scsi_device.sector_size is unsigned (int), factor should be unsigned
int, too.
