The expected message type can be global as they never change
during the after negotiation process.
This will replace smbd_response->type and smb_direct_recvmsg->type
in future.

Calling enqueue_reassembly() and wake_up_interruptible(&info->wait_reassembly_queue)
or put_receive_buffer() means the response/data_transfer pointer might
get re-used by another thread, which means these should be
the last operations before calling return.

We should call put_receive_buffer() before waking up the callers.
For the internal error case of response->type being unexpected,
we now also call smbd_disconnect_rdma_connection() instead
of not waking up the callers at all.
Note that the SMBD_TRANSFER_DATA case still has problems,
which will be addressed in the next commit in order to make
it easier to review this one.

ib_dma_map_single already
In case of failures either ib_dma_map_single() might not be called yet
or ib_dma_unmap_single() was already called.
We should make sure put_receive_buffer() only calls
ib_dma_unmap_single() if needed.

There's no need to maintain two lists, we can just
have a single list of receive buffers, which are free to use.
It just added unneeded complexity and resulted in
ib_dma_unmap_single() not being called from recv_done()
for empty keepalive packets.

smbd_disconnect_rdma_connection()
We should call ib_dma_unmap_single() and mempool_free() before calling
smbd_disconnect_rdma_connection().
And smbd_disconnect_rdma_connection() needs to be the last function to
call as all other state might already be gone after it returns.

The root cause is an initialization order problem. The lock is declared
as a global variable and intended to be initialized during module startup.
However, the procfs entry that uses this lock can be accessed by userspace
before the spin_lock_init() call has run. This creates a race window where
reading the proc file will attempt to use the lock before it is
initialized, leading to the crash.
For a global lock with a static lifetime, the correct and robust approach
is to use compile-time initialization.

This is step 3/4 of a patch series to fix mid_q_entry memory leaks
caused by race conditions in callback execution.
Replace the mid_flags bitmask with dedicated boolean fields to
simplify locking logic and improve code readability:
- Replace MID_DELETED with bool deleted_from_q
- Replace MID_WAIT_CANCELLED with bool wait_cancelled
- Remove mid_flags field entirely
The new boolean fields have clearer semantics:
- deleted_from_q: whether mid has been removed from pending_mid_q
- wait_cancelled: whether request was cancelled during wait
This change reduces memory usage (from 4-byte bitmask to 2 boolean
flags) and eliminates confusion about which lock protects which
flag bits, preparing for per-mid locking in the next patch.

This is step 2/4 of a patch series to fix mid_q_entry memory leaks
caused by race conditions in callback execution.
Add a dedicated mid_counter_lock to protect current_mid counter,
separating it from mid_queue_lock which protects pending_mid_q
operations. This reduces lock contention and prepares for finer-
grained locking in subsequent patches.
Changes:
- Add TCP_Server_Info->mid_counter_lock spinlock
- Rename CurrentMid to current_mid for consistency
- Use mid_counter_lock to protect current_mid access
- Update locking documentation in cifsglob.h
This separation allows mid allocation to proceed without blocking
queue operations, improving performance under heavy load.

This is step 1/4 of a patch series to fix mid_q_entry memory leaks
caused by race conditions in callback execution.
The current mid_lock name is somewhat ambiguous about what it protects.
To prepare for splitting this lock into separate, more granular locks,
this patch renames mid_lock to mid_queue_lock to clearly indicate its
specific responsibility for protecting the pending_mid_q list and
related queue operations.
No functional changes are made in this patch - it only prepares the
codebase for the lock splitting that follows.
- mid_queue_lock for queue operations
- mid_counter_lock for mid counter operations
- per-mid locks for individual mid state management

provides a couple of page->folio conversions.
"mm: per-node proactive reclaim" (Davidlohr Bueso)
implements a per-node control of proactive reclaim - beyond the
current memcg-based implementation.
"mm/damon: remove damon_callback" (SeongJae Park)
replaces the damon_callback interface with a more general and
powerful damon_call()+damos_walk() interface.
"mm/mremap: permit mremap() move of multiple VMAs" (Lorenzo Stoakes)
implements a number of mremap cleanups (of course) in preparation
for adding new mremap() functionality: newly permit the remapping

provides (and uses) a means by which debug-style functions can grab
a copy of a pageframe and inspect it locklessly without tripping
over the races inherent in operating on the live pageframe
directly.
"use per-vma locks for /proc/pid/maps reads" (Suren Baghdasaryan)
addresses the large contention issues which can be triggered by
reads from that procfs file. Latencies are reduced by more than
half in some situations. The series also introduces several new
selftests for the /proc/pid/maps interface.
"__folio_split() clean up" (Zi Yan)
cleans up __folio_split()!
"Optimize mprotect() for large folios" (Dev Jain)
provides some quite large (>3x) speedups to mprotect() when dealing
with large folios.
"selftests/mm: reuse FORCE_READ to replace "asm volatile("" : "+r" (XXX));" and some cleanup" (wang lian)
does some cleanup work in the selftests code.
"tools/testing: expand mremap testing" (Lorenzo Stoakes)
extends the mremap() selftest in several ways, including adding
more checking of Lorenzo's recently added "permit mremap() move of
multiple VMAs" feature.
"selftests/damon/sysfs.py: test all parameters" (SeongJae Park)
extends the DAMON sysfs interface selftest so that it tests all
possible user-requested parameters. Rather than the present minimal
subset"

Pull clk updates from Stephen Boyd:
"This is the usual collection of primarily clk driver updates.
The big part of the diff is all the new Qualcomm clk drivers added for
a few SoCs they're working on. The other two vendors with significant
work this cycle are Renesas and Amlogic. Renesas adds a bunch of clks
to existing drivers and supports some new SoCs while Amlogic is
starting a significant refactoring to simplify their code.
The core framework gained a pair of helpers to get the 'struct device'
or 'struct device_node' associated with a 'struct clk_hw'. Some
associated KUnit tests were added for these simple helpers as well.
Beyond that core change there are lots of little fixes throughout the
clk drivers for the stuff we see every day, wrong clk driver data that
affects tree topology or supported frequencies, etc. They're not found
until the clks are actually used by some consumer device driver.
New Drivers:
- Global, display, gpu, video, camera, tcsr, and rpmh clock
controller for the Qualcomm Milos SoC
- Camera, display, GPU, and video clock controllers for Qualcomm
QCS615
- Video clock controller driver for Qualcomm SM6350
- Camera clock controller driver for Qualcomm SC8180X
- I3C clocks and resets on Renesas RZ/G3E
- Expanded Serial Peripheral Interface (xSPI) clocks and resets on
Renesas RZ/V2H(P) and RZ/V2N
- SPI (RSPI) clocks and resets on Renesas RZ/V2H(P)
- SDHI and I2C clocks on Renesas RZ/T2H and RZ/N2H
- Ethernet clocks and resets on Renesas RZ/G3E
- Initial support for the Renesas RZ/T2H (R9A09G077) and RZ/N2H
(R9A09G087) SoCs
- Ethernet clocks and resets on Renesas RZ/V2H and RZ/V2N
- Timer, I2C, watchdog, GPU, and USB2.0 clocks and resets on Renesas

Updates:
- Support atomic PWMs in the PWM clk driver
- clk_hw_get_dev() and clk_hw_get_of_node() helpers
- Replace round_rate() with determine_rate() in various clk drivers
- Convert clk DT bindings to DT schema format for DT validation
- Various clk driver cleanups and refactorings from static analysis
tools and possibly real humans

Pull pwm fixes from Uwe Kleine-König:
"Two fixes for the mediatek and the imx-tpm driver. Both are old
(v4.12-rc1 and v5.2-rc1 respectively).
The mediatek issue is that both period and duty_cycle were configured
to higher values than requested. For most applications the period part
is no tragedy, but a PWM that is configured for duty_cycle = 0 should
really emit a constant inactive signal. That was noticed by an LED not
being completely off in this case (two commits for one fix: a
preparatory one and the actual fix in the second one).
For the imx-tpm PWM driver the fixed issue is that the first period is
quite a bit too long under some circumstances. So it might take up to
UINT32_MAX << 7 clock ticks until the PWM starts toggling. With an
assumed input clock rate of 166 MHz (completely made up) that's 55
minutes"

Pull iommufd updates from Jason Gunthorpe:
"This broadly brings the assigned HW command queue support to iommufd.
This feature is used to improve SVA performance in VMs by avoiding
paravirtualization traps during SVA invalidations.
Along the way I think some of the core logic is in a much better state
to support future driver backed features.
Summary:
- IOMMU HW now has features to directly assign HW command queues to a
guest VM. In this mode the command queue operates on a limited set
of invalidation commands that are suitable for improving guest
invalidation performance and easy for the HW to virtualize.
This brings the generic infrastructure to allow IOMMU drivers to
expose such command queues through the iommufd uAPI, mmap the
doorbell pages, and get the guest physical range for the command
queue ring itself.
- An implementation for the NVIDIA SMMUv3 extension "cmdqv" is built
on the new iommufd command queue features. It works with the
existing SMMU driver support for cmdqv in guest VMs.
- Many precursor cleanups and improvements to support the above
cleanly, changes to the general ioctl and object helpers, driver
support for VDEVICE, and mmap pgoff cookie infrastructure.
- Sequence VDEVICE destruction to always happen before VFIO device
destruction. When using the above type features, and also in future
confidential compute, the internal virtual device representation
becomes linked to HW or CC TSM configuration and objects. If a VFIO
device is removed from iommufd those HW objects should also be
cleaned up to prevent a sort of UAF. This became important now that
we have HW backing the VDEVICE.
- Fix one syzkaller found error related to math overflows during iova
allocation"

Pull LED updates from Lee Jones:
"Improvements & Fixes:
- A fix for QCOM Flash to prevent incorrect register access when the
driver is re-bound. This is solved by duplicating a static register
array during the probe function, which prevents register addresses
from being miscalculated after multiple binds
- The LP50xx driver now correctly handles the 'reg' property in
device tree child nodes to ensure the multi_index is set correctly.
This prevents issues where LEDs could be controlled incorrectly if
the device tree nodes were processed in a different order. An error
is returned if the reg property is missing or out of range
- Add a Kconfig dependency on between TPS6131x and
V4L2_FLASH_LED_CLASS to prevent a build failure when the driver is
built-in and the V4L2 flash infrastructure is a loadable module
- Fix a potential buffer overflow warning in PCA955x reported by
older GCC versions by using a more precise format specifier when
creating the default LED label.
Cleanups & Refactoring:
- Correct the MAINTAINERS file entry for the TPS6131X flash LED
driver to point to the correct device tree binding file name
- Fix a comment in the Flash Class for the flash_timeout setter to
"flash timeout" from "flash duration" for accuracy
- The of_led_get() function is no longer exported as it has no users
outside of its own module.
Removals:
- Revert the commit to configure LED blink intervals for hardware
offload in the Netdev Trigger. This change was found to break
existing PHY drivers by putting their LEDs into a permanent,
unconditional blinking state.
Device Tree Bindings Updates:
- Update the binding for LP50xx to document that the child reg
property is the index within the LED bank. The example was also
updated to use correct values
- Update the JNCP5623 binding to add 0x39 as a valid I2C address, as

drivers
- Alphabetize Kconfig entries for Cirrus Logic and Maxim drivers
- Remove unused fields from the 'tps65219' struct
- Update several MFD-related headers to follow the 'Include What You
Use' (IWYU) principle.

which is now superseded by the new MFD-based adp5585-keys driver
- Remove the unused twl6030_mmc_card_detect() functions and
associated header declarations
- Remove the now unused pcf50633/core.h header file
- Remove the fsl,imx8qxp-csr device tree binding, which was being
used incorrectly.

* Raw NAND changes:
Various controller drivers received minor fixes like DMA mapping checks,
better timing derivations or bitflip statistics.
It has also been discovered that some Hynix NAND flashes were not
supporting read-retries, which is not properly supported.
* SPI NAND changes:
In order to support high-speed modes, certain chips need extra
configuration like adding more dummy cycles. This is now possible,
especially on Winbond chips.
Aside from that, Gigadevice gets support for a new chip (GD5F1GM9).

SPI NOR changes for 6.17
Notable changes:
- Fix exiting 4-byte addressing on Infineon SEMPER flashes. These
flashes do not support the standard EX4B opcode (E9h), and use a
vendor-specific opcode (B8h) instead.
- Fix unlocking of flashes that are write-protected at power-on. This
was caused by using an uninitialized mtd_info in
spi_nor_try_unlock_all().

Pull documentation updates from Jonathan Corbet:
"It has been a relatively busy cycle for docs, especially the build
system:
- The Perl kernel-doc script was added to 2.3.52pre1 just after the
turn of the millennium. Over the following 25 years, it accumulated
a vast amount of cruft, all in a language few people want to deal
with anymore. Mauro's Python replacement in 6.16 faithfully
reproduced all of the cruft in the hope of avoiding regressions.
Now that we have a more reasonable code base, though, we can work
on cleaning it up; many of the changes this time around are toward
that end.
- A reorganization of the ext4 docs into the usual TOC format.
- Various Chinese translations and updates.
- A new script from Mauro to help with docs-build testing.
- A new document for linked lists
- A sweep through MAINTAINERS fixing broken GitHub git:// repository
links.
...and lots of fixes and updates"
