Pull regmap updates from Mark Brown:
"Another small update for regmap, we have one new feature plus a little
bit of cleanup:
- Support for sparseness information in the flat cache, allowing
users that really need the performance properties it provides to
benefit from the interface and startup time improvements that
sparsness provides without needing to go all the way to a more
fancy data structure
- Cleanup work from Andy Shevchenko, refactoring the cache interface
in preparation for some future stuff he's working on"

Pull mtd updates from Miquel Raynal:
"Core MTD changes:
- We must ignore error -ENOENT from parsers on subpartitions which is
a legitimate return value
- PM support is added to the intel-dg driver
Raw NAND changes:
- The major change in this is the support for the Allwinner H616 NAND
controller, which lead to numerous changes and cleanups in the
driver.
- Another notable change in this driver is the use of field_get() and
field_prep(), but since the global support for this helpers is
going to be merged in the same release as we start using these
helpers, we undefine them in the first place to avoid warnings.
- Marvell drivers layout handling changes have also landed, they fix
previous definitions and abuses that have been made previously,
which implied to relax the ECC parameters validation in the core a
bit.
- The Cadence NAND controller driver gets NV-DDR interface support.
SPI NAND changes:
- Support for FudanMicro FM25S01BI3 and ESMT F50L1G41LC is added.
SPI NOR changes:
- Fix SMPT parsing for S25FS-S flash family. They report variable
dummy cycles for reads. This results in the default of 0 being
used. This works for other Infineon chips, but not for the S25FS-S
family. They need 8 dummy cycles. Add fixup hooks to specify that.
Also add fixup hooks to fix incorrect map ID data in SFDP.
- Add support for a bunch of Winbond flashes. Their block protection
information is not discoverable, so they need to have an entry in
the flash tables to describe that.
- Some cleanups for Micron flash support.
- Add support for Micron mt35xu01gbba.
- Some SPI controllers like the Intel one on the PCI bus do not
support the read CR opcode (0x35). Do not use the opcode if the
controller does not support it.
Aside from these main changes, there is the usual load of API updates,
kdoc fixes, potential memory leaks fixes, etc"

Add a new helper function blk_rq_nr_bvec() that returns the number of
bvecs in a request. This count represents the number of iterations
rq_for_each_bvec() would perform on a request.
Drivers need to pre-allocate bvec arrays before iterating through
a request's bvecs. Currently, they manually count bvecs using
rq_for_each_bvec() in a loop, which is repetitive. The new helper
centralizes this logic.
This pattern exists in loop and zloop drivers, where multi-bio requests
require copying bvecs into a contiguous array before creating
an iov_iter for file operations.
Update loop and zloop drivers to use the new helper, eliminating
duplicate code.
This patch also provides a clear API to avoid any potential misuse of
blk_nr_phys_segments() for calculating the bvecs since, one bvec can
have more than one segments and use of blk_nr_phys_segments() can
lead to extra memory allocation :-
[ 6155.673749] nullb_bio: 128K bio as ONE bvec: sector=0, size=131072
[ 6155.673846] null_blk: #### null_handle_data_transfer:1375
[ 6155.673850] null_blk: nr_bvec=1 blk_rq_nr_phys_segments=2
[ 6155.674263] null_blk: #### null_handle_data_transfer:1375

All functions used for signaling a fence return an error code whose sole
purpose is to tell whether a fence was already signaled.
This is racy and has been used by almost no party in the kernel, and the
few users have been removed in preceding cleanup commits.
Turn all signaling-functions into void-functions.

The overwhelming majority of users of dma_fence signaling functions
don't care about whether the fence had already been signaled by someone
else. Therefore, the return code shall be removed from those functions.
For the few users who rely on the check, a new, specialized function
shall be provided.
Add dma_fence_check_and_signal(), which signals a fence if it had not
yet been signaled, and informs the user about that.
Add a counter part, dma_fence_check_and_signal_locked(), which doesn't
take the spinlock.

The dma_fence framework checks at many places whether the signaled flag
of a fence is already set. The code can be simplified and made more
readable by providing a helper function for that.
Add dma_fence_test_signaled_flag(), which only checks whether a fence is
signaled. Use it internally.

Pull hfs/hfsplus updates from Viacheslav Dubeyko:
"Several fixes for syzbot reported issues, HFS/HFS+ fixes of xfstests
failures, Kunit-based unit-tests introduction, and code cleanup:
- Dan Carpenter fixed a potential use-after-free issue in
hfs_correct_next_unused_CNID() method. Tetsuo Handa has made nice
fix of syzbot reported issue related to incorrect inode->i_mode
management if volume has been corrupted somehow. Yang Chenzhi has
made really good fix of potential race condition in
__hfs_bnode_create() method for HFS+ file system.
- Several fixes to xfstests failures. Particularly, generic/070,
generic/073, and generic/101 test-cases finish successfully for the
case of HFS+ file system right now.
- HFS and HFS+ drivers share multiple structures of on-disk layout
declarations. Some structures are used without any change. However,
we had two independent declarations of the same structures in HFS
and HFS+ drivers.
The on-disk layout declarations have been moved into
include/linux/hfs_common.h with the goal to exclude the
declarations duplication and to keep the HFS/HFS+ on-disk layout
declarations in one place.
Also, this patch prepares the basis for creating a hfslib that can
aggregate common functionality without necessity to duplicate the
same code in HFS and HFS+ drivers.
- HFS/HFS+ really need unit-tests because of multiple xfstests
failures. The first two patches introduce Kunit-based unit-tests
for the case string operations in HFS/HFS+ file system drivers"

Pull io_uring updates from Jens Axboe:
- Unify how task_work cancelations are detected, placing it in the
task_work running state rather than needing to check the task state
- Series cleaning up and moving the cancelation code to where it
belongs, in cancel.c
- Cleanup of waitid and futex argument handling
- Add support for mixed sized SQEs. 6.18 added support for mixed sized
CQEs, improving flexibility and efficiency of workloads that need big
CQEs. This adds similar support for SQEs, where the occasional need
for a 128b SQE doesn't necessitate having all SQEs be 128b in size
- Introduce zcrx and SQ/CQ layout queries. The former returns what zcrx
features are available. And both return the ring size information to
help with allocation size calculation for user provided rings like
IORING_SETUP_NO_MMAP and IORING_MEM_REGION_TYPE_USER
- Zcrx updates for 6.19. It includes a bunch of small patches,
IORING_REGISTER_ZCRX_CTRL and RQ flushing and David's work on sharing
zcrx b/w multiple io_uring instances
- Series cleaning up ring initializations, notable deduplicating ring
size and offset calculations. It also moves most of the checking
before doing any allocations, making the code simpler
- Add support for getsockname and getpeername, which is mostly a
trivial hookup after a bit of refactoring on the networking side

The recent increase in the number of Segment Summary Area (SSA) entries
from 512 to 2048 was an unintentional change in logic of 16kb block
support. This commit corrects the issue.
To better utilize the space available from the erroneous 2048-entry
calculation, we are implementing a solution to share the currently
unused SSA space with neighboring segments. This enhances overall
SSA utilization without impacting the established 8MB segment size.

Pull networking updates from Jakub Kicinski:
"Core & protocols:
- Replace busylock at the Tx queuing layer with a lockless list.
Resulting in a 300% (4x) improvement on heavy TX workloads, sending
twice the number of packets per second, for half the cpu cycles.
- Allow constantly busy flows to migrate to a more suitable CPU/NIC
queue.
Normally we perform queue re-selection when flow comes out of idle,
but under extreme circumstances the flows may be constantly busy.
Add sysctl to allow periodic rehashing even if it'd risk packet
reordering.
- Optimize the NAPI skb cache, make it larger, use it in more paths.
- Attempt returning Tx skbs to the originating CPU (like we already
did for Rx skbs).
- Various data structure layout and prefetch optimizations from Eric.
- Remove ktime_get() from the recvmsg() fast path, ktime_get() is
sadly quite expensive on recent AMD machines.
- Extend threaded NAPI polling to allow the kthread busy poll for
packets.
- Make MPTCP use Rx backlog processing. This lowers the lock
pressure, improving the Rx performance.
- Support memcg accounting of MPTCP socket memory.
- Allow admin to opt sockets out of global protocol memory accounting
(using a sysctl or BPF-based policy). The global limits are a poor
fit for modern container workloads, where limits are imposed using
cgroups.
- Improve heuristics for when to kick off AF_UNIX garbage collection.
- Allow users to control TCP SACK compression, and default to 33% of
RTT.
- Add tcp_rcvbuf_low_rtt sysctl to let datacenter users avoid
unnecessarily aggressive rcvbuf growth and overshot when the
connection RTT is low.
- Preserve skb metadata space across skb_push / skb_pull operations.
- Support for IPIP encapsulation in the nftables flowtable offload.
- Support appending IP interface information to ICMP messages (RFC
5837).
- Support setting max record size in TLS (RFC 8449).
- Remove taking rtnl_lock from RTM_GETNEIGHTBL and RTM_SETNEIGHTBL.
- Use a dedicated lock (and RCU) in MPLS, instead of rtnl_lock.
- Let users configure the number of write buffers in SMC.
- Add new struct sockaddr_unsized for sockaddr of unknown length,
from Kees.
- Some conversions away from the crypto_ahash API, from Eric Biggers.
- Some preparations for slimming down struct page.
- YAML Netlink protocol spec for WireGuard.

defined by the OPEN Alliance's "Advanced diagnostic features for
100BASE-T1 automotive Ethernet PHYs" specification.
- Add DPLL phase-adjust-gran pin attribute (and implement it in
zl3073x).
- Refactor xfrm_input lock to reduce contention when NIC offloads
IPsec and performs RSS.
- Add info to devlink params whether the current setting is the
default or a user override. Allow resetting back to default.
- Add standard device stats for PSP crypto offload.
- Leverage DSA frame broadcast to implement simple HSR frame
duplication for a lot of switches without dedicated HSR offload.

git://git.kernel.org/pub/scm/linux/kernel/git/tj/sched_ext
Pull sched_ext updates from Tejun Heo:
- Improve recovery from misbehaving BPF schedulers.
When a scheduler puts many tasks with varying affinity restrictions
on a shared DSQ, CPUs scanning through tasks they cannot run can
overwhelm the system, causing lockups.
Bypass mode now uses per-CPU DSQs with a load balancer to avoid this,
and hooks into the hardlockup detector to attempt recovery.
Add scx_cpu0 example scheduler to demonstrate this scenario.
- Add lockless peek operation for DSQs to reduce lock contention for
schedulers that need to query queue state during load balancing.
- Allow scx_bpf_reenqueue_local() to be called from anywhere in
preparation for deprecating cpu_acquire/release() callbacks in favor
of generic BPF hooks.
- Prepare for hierarchical scheduler support: add
scx_bpf_task_set_slice() and scx_bpf_task_set_dsq_vtime() kfuncs,
make scx_bpf_dsq_insert*() return bool, and wrap kfunc args in
structs for future aux__prog parameter.
- Implement cgroup_set_idle() callback to notify BPF schedulers when a
cgroup's idle state changes.
- Fix migration tasks being incorrectly downgraded from
stop_sched_class to rt_sched_class across sched_ext enable/disable.
Applied late as the fix is low risk and the bug subtle but needs
stable backporting.
- Various fixes and cleanups including cgroup exit ordering,
SCX_KICK_WAIT reliability, and backward compatibility improvements.
