The iser target is the RDMA requester and the iser initiator is the
RDMA responder. In order to determine the max inflight RDMA READ requests
to set on the QP (initiator_depth), it should take the min between the
initiator published initiator_depth and the max inflight rdma read
requests its local HCA support (max_qp_init_rd_atom).
The target will never handle incoming RDMA READ requests so no need to
set responder_resources.

rdma_disconnect may be called in 2 code flows:
- isert_wait_conn: disconnect initiated be the target
- disconnected_handler: disconnect invoked by the initiator
In case isert_conn->disconnect is true then rdma_disconnect
was called in disconnected handler, no need to call it again
from isert_wait_conn.

disconnected_handler is invoked on several CM events (such
as DISCONNECTED, DEVICE_REMOVAL, TIMEWAIT_EXIT...). Since
multiple events can occur while before isert_free_conn is
invoked, we might put all isert_conn references and free
the connection too early.

In case the connection didn't reach connected state, disconnected
handler will never be invoked thus the second kref_put on

A previous commit 5493b31f0b55 ("PCI: Add pci_ignore_hotplug() to ignore

Pull vfs fixes from Al Viro:
"double iput() on failure exit in lustre, racy removal of spliced
dentries from ->s_anon in __d_materialise_dentry() plus a bunch of

The RCU pathwalk fixes end up fixing a couple of cases where we
incorrectly dropped out of RCU walking, due to incorrect initialization
and testing of the sequence locks in some corner cases. Since dropping
out of RCU walk mode forces the slow locked accesses, those corner cases
slowed down quite dramatically.

If touchscreen mode is enabled and a conversion is requested on another
channel, the result in the last converted data register can be a
touchscreen relative value. Starting a conversion involves to do a
conversion for all active channel. It starts with ADC channels and ends
with touchscreen channels. Then if ADC_LCD register is not read quickly,
its content may be a touchscreen conversion.
To remove this temporal constraint, the conversion value is taken from
the channel data register.

Now CS GPIOs are requested from struct spi_master.setup() callback
and that causes failures when Client SPI device is getting accessed
through SPIDEV driver. The failure happens, because .setup() callback
may be called many times from IOCTL handler and when it's called
second time gpio_request() will fail and return -EBUSY.
Hence, fix it by moving CS GPIOs requesting code in .probe().

We print way too many messages like this:
pci 0000:00:00.0: no hotplug settings from platform
pci 0000:00:00.0: using default PCI settings
This usually happens when the platform doesn't supply an ACPI _HPP method,
but the method is optional, so there's no point in warning about it.
Not only are the messages useless, but we call pci_configure_slot() far too
many times, so they're repeated many times. I'll fix the overuse of
pci_configure_slot() too, but that will wait until the next merge window.
For now, just remove both log messages.

We are getting more and more reports about LG laptops not having
functioning keyboard if we try to deactivate keyboard during probe.
Given that having keyboard deactivated is merely "nice to have"
instead of a hard requirement for probing, let's disable it on all
LG boxes instead of trying to hunt down particular models.
This change is prompted by patches trying to add "LG Electronics"/"ROCKY"
and "LG Electronics"/"LW60-F27B" to the DMI list.

Resuming from hibernate (S4) will restart and re-initialize xHC.
The device contexts are freed and will be re-allocated later during device reset.
Usb core will disable link pm in device resume before device reset, which will
try to change the max exit latency, accessing the device contexts before they are re-allocated.
There is no need to zero (disable) the max exit latency when disabling hw lpm
for a freshly re-initialized xHC. So check that device context exists before
doing anything. The max exit latency will be set again after device reset when usb core
enables the link pm.

The xhci driver will OOPS on resume from S2/S3 if dma_alloc_coherent()
is out of memory. This is a result of two things:
1. xhci_mem_cleanup() in xhci-mem.c free's xhci->lpm_command if
it's not NULL, but doesn't set it to NULL after the free.
2. xhci_mem_cleanup() is called twice on resume, once for normal
restart and once from xhci_mem_init() if dma_alloc_coherent() fails,
resulting in a free of xhci->lpm_command that has already been freed.
The fix is to set xhci->lpm_command to NULL after freeing it.

The Iomega Jaz USB Adapter is a SCSI-USB converter cable. The hardware

Pull ACPI and power management fixes from Rafael Wysocki:
"These are regression fixes (cpufreq, ACPI battery) and fixes for stuff
that never worked correctly (ACPI RTC operation region handler and PM
domain implementation in the ACPI LPSS driver).
Specifics:
- Fix for the cpufreq Operation Performance Points (OPP) code where a
recent commit added a kcalloc() call with an incorrect ordering of
arguments. From Anand Moon.
- Reverts of two ACPI battery commits that caused incorrect
diagnostic information to be printed to dmesg in some cases from
Bjørn Mork.
- Fix for the ACPI RTC operation region handler that applied the &
operator to an argument already representing an address and that
caused it to overwrite its own argument instead of writing to the
address contained in it as expected. From Chun-Yi Lee.
- Fix for the PM domain implementation in the ACPI LPSS (Low-Power
Subsystem) driver where one callback pointer pointed to a wrong
routine and one was NULL, but it shouldn't. From Fu Zhonghui"
