https://kernelnewbies.org/MatthewWilcox/Memdescs and
https://blogs.oracle.com/linux/post/introducing-memdesc.

to the page allocator code.

makes rather a lot of adjustments at various nth_page() callsites,
eventually permitting the removal of that undesirable helper function.
- The 2 patch series "introduce kasan.write_only option in hw-tags" from

split_pte_mapped_thp improvements" from David Hildenbrand adds a fix and
some cleanups to the thp selftesting code.
- The 14 patch series "mm, swap: introduce swap table as swap cache
(phase I)" from Chris Li and Kairui Song is the first step along the
path to implementing "swap tables" - a new approach to swap allocation
and state tracking which is expected to yield speed and space
improvements. This patchset itself yields a 5-20% performance benefit
in some situations.
- The 3 patch series "Some ptdesc cleanups" from Matthew Wilcox utilizes
the new memdesc layer to clean up the ptdesc code a little.
- The 3 patch series "Fix va_high_addr_switch.sh test failure" from

memory allocation profiling feature.

cleanups in preparation for more memdesc work.

warnings" from Muhammad Anjum adds that compiler check to selftests code
and fixes the fallout, by removing dead code.
- The 10 patch series "Improvements to Victim Process Thawing and OOM
Reaper Traversal Order" from zhongjinji makes a number of improvements
in the OOM killer: mainly thawing a more appropriate group of victim
threads so they can release resources.

from SeongJae Park is a bunch of small and unrelated fixups for DAMON.

userspace clients of the DAMON_STAT information.
- The 2 patch series "Expand scope of khugepaged anonymous collapse"
from Dev Jain removes some constraints on khubepaged's collapsing of
anon VMAs. It also increases the success rate of MADV_COLLAPSE against
an anon vma.
- The 2 patch series "mm: do not assume file == vma->vm_file in
compat_vma_mmap_prepare()" from Lorenzo Stoakes moves us further towards
removal of file_operations.mmap(). This patchset concentrates upon
clearing up the treatment of stacked filesystems.
- The 6 patch series "mm: Improve mlock tracking for large folios" from
Kiryl Shutsemau provides some fixes and improvements to mlock's tracking
of large folios. /proc/meminfo's "Mlocked" field became more accurate.
- The 2 patch series "mm/ksm: Fix incorrect accounting of KSM counters
during fork" from Donet Tom fixes several user-visible KSM stats
inaccuracies across forks and adds selftest code to verify these
counters.

mm_slot handling.

Pull block updates from Jens Axboe:
- NVMe pull request via Keith:
- FC target fixes (Daniel)
- Authentication fixes and updates (Martin, Chris)
- Admin controller handling (Kamaljit)
- Target lockdep assertions (Max)
- Keep-alive updates for discovery (Alastair)
- Suspend quirk (Georg)
- MD pull request via Yu:
- Add support for a lockless bitmap.
A key feature for the new bitmap are that the IO fastpath is
lockless. If a user issues lots of write IO to the same bitmap
bit in a short time, only the first write has additional overhead
to update bitmap bit, no additional overhead for the following
writes.
By supporting only resync or recover written data, means in the
case creating new array or replacing with a new disk, there is no
need to do a full disk resync/recovery.
- Switch ->getgeo() and ->bios_param() to using struct gendisk rather
than struct block_device.
- Rust block changes via Andreas. This series adds configuration via
configfs and remote completion to the rnull driver. The series also
includes a set of changes to the rust block device driver API: a few
cleanup patches, and a few features supporting the rnull changes.
The series removes the raw buffer formatting logic from
`kernel::block` and improves the logic available in `kernel::string`
to support the same use as the removed logic.
- floppy arch cleanups
- Reduce the number of dereferencing needed for ublk commands
- Restrict supported sockets for nbd. Mostly done to eliminate a class
of issues perpetually reported by syzbot, by using nonsensical socket
setups.
- A few s390 dasd block fixes
- Fix a few issues around atomic writes
- Improve DMA interation for integrity requests
- Improve how iovecs are treated with regards to O_DIRECT aligment
constraints.
We used to require each segment to adhere to the constraints, now
only the request as a whole needs to.
- Clean up and improve p2p support, enabling use of p2p for metadata
payloads
- Improve locking of request lookup, using SRCU where appropriate
- Use page references properly for brd, avoiding very long RCU sections
- Fix ordering of recursively submitted IOs
- Clean up and improve updating nr_requests for a live device
- Various fixes and cleanups

Merge the mmc fixes for v6.17-rc[n] into the next branch, to allow them to

Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
Rename the inner 'frm' variable to 'resp_frm' in the write path of
mmc_route_rpmb_frames() to avoid shadowing the outer 'frm' variable.
The function declares 'frm' at function scope pointing to the request
frame, but then redeclares another 'frm' variable inside the write
block pointing to the response frame. This shadowing makes the code
confusing and error-prone.
Using 'resp_frm' for the response frame makes the distinction clear
and improves code readability.

For Qualcomm SoCs which needs level shifter for SD card, extra delay is
seen on receiver data path.
To compensate this delay enable tuning for SDR50 mode for targets which
has level shifter. SDHCI_SDR50_NEEDS_TUNING caps will be set for targets
with level shifter on Qualcomm SOC's.

block: switch ->getgeo() to struct gendisk
scsi: switch ->bios_param() to passing gendisk
scsi: switch scsi_bios_ptable() and scsi_partsize() to gendisk
The era of hand-rolled HIWORD_UPDATE macros is over, at least for those
drivers that use constant masks.
Switch to the new FIELD_PREP_WM16 macro in hw_bitfield.h, which has
error checking. Instead of redefining the driver's HIWORD_UPDATE macro
in this case, replace the two only instances of it with the new macro,
as I could test that they result in an equivalent value.

Starting with commit f99508074e ("PM: domains: Detach on
device_unbind_cleanup()"), there is no longer a need to call
dev_pm_domain_detach() in the bus remove function. The
device_unbind_cleanup() function now handles this to avoid
invoking devres cleanup handlers while the PM domain is
powered off, which could otherwise lead to failures as
described in the above-mentioned commit.
Drop the explicit dev_pm_domain_detach() call and rely instead
on the flags passed to dev_pm_domain_attach() to power off the
domain.

Use the modern PM macros for the suspend and resume functions to be
automatically dropped by the compiler when CONFIG_PM or
CONFIG_PM_SLEEP are disabled, without having to use #ifdef guards.
This has the advantage of always compiling these functions in,
independently of any Kconfig option. Thanks to that, bugs and other
regressions are subsequently easier to catch.
