Pull ext4 updates from Ted Ts'o:
"New features and improvements for the ext4 file system
- Avoid unnecessary cache invalidation in the extent status cache
(es_cache) when adding extents to be cached in the es_cache and we
are not changing the extent tree
- Add a sysfs parameter, err_report_sec, to control how frequently to
log a warning message that file system inconsistency has been
detected (Previously we logged the warning message every 24 hours)
- Avoid unnecessary forced ordered writes when appending to a file
when delayed allocation is enabled
- Defer splitting unwritten extents to I/O completion to improve
write performance of concurrent direct I/O writes to multiple files
- Refactor and add kunit tests to the extent splitting and conversion
code paths
Various Bug Fixes:
- Fix a panic when the debugging DOUBLE_CHECK macro is defined
- Avoid using fast commit for rare and complex file system operations
to make fast commit easier to reason about. This can also avoid
some corner cases that could result in file system inconsistency if
there is a crash between the fast commit before a subsequent full
commit
- Fix memory leaks in error paths
- Fix a false positive reports caused when running stress tests using
mixed huge-page workloads caused by a race between page migration
and bitmap updates
- Fix a potential recursion into file system reclaim when evicting an
inode when fast commit is enabled
- Fix a warning caused by a potential double decrement to the dirty
clusters counter when executing FS_IOC_SHUTDOWN when running a
stress test
- Enable mballoc optimized scanning regardless whether the inode is
using indirect blocks or extent trees to map blocks"

Pull nfsd updates from Chuck Lever:
"Neil Brown and Jeff Layton contributed a dynamic thread pool sizing
mechanism for NFSD. The sunrpc layer now tracks minimum and maximum
thread counts per pool, and NFSD adjusts running thread counts based
on workload: idle threads exit after a timeout when the pool exceeds
its minimum, and new threads spawn automatically when all threads are
busy. Administrators control this behavior via the nfsdctl netlink
interface.
Rick Macklem, FreeBSD NFS maintainer, generously contributed server-
side support for the POSIX ACL extension to NFSv4, as specified in
draft-ietf-nfsv4-posix-acls. This extension allows NFSv4 clients to
get and set POSIX access and default ACLs using native NFSv4
operations, eliminating the need for sideband protocols. The feature
is gated by a Kconfig option since the IETF draft has not yet been
ratified.
Chuck Lever delivered numerous improvements to the xdrgen tool. Error
reporting now covers parsing, AST transformation, and invalid
declarations. Generated enum decoders validate incoming values against
valid enumerator lists. New features include pass-through line support
for embedding C directives in XDR specifications, 16-bit integer
types, and program number definitions. Several code generation issues
were also addressed.
When an administrator revokes NFSv4 state for a filesystem via the
unlock_fs interface, ongoing async COPY operations referencing that
filesystem are now cancelled, with CB_OFFLOAD callbacks notifying
affected clients.
The remaining patches in this pull request are clean-ups and minor
optimizations. Sincere thanks to all contributors, reviewers, testers,
and bug reporters who participated in the v7.0 NFSD development cycle"

In ovpn_net_xmit, after GSO segmentation and segment processing, the
first segment on the list is used to increment VPN TX statistics, which
fails to account for any subsequent segments in the chain.
Fix this by accumulating the length of every segment that successfully
passes skb_share_check into a tx_bytes variable. This ensures the peer
statistics accurately reflect the total data volume sent, regardless of
whether the original packet was segmented.

When building the skb_list in ovpn_net_xmit, skb_share_check will free
the original skb if it is shared. The current implementation continues
to use the stale skb pointer for subsequent operations:
- peer lookup,
- skb_dst_drop (even though all segments produced by skb_gso_segment
will have a dst attached),
- ovpn_peer_stats_increment_tx.
Fix this by moving the peer lookup and skb_dst_drop before segmentation
so that the original skb is still valid when used. Return early if all
segments fail skb_share_check and the list ends up empty.
Also switch ovpn_peer_stats_increment_tx to use skb_list.next; the next
patch fixes the stats logic.

During initialization, we override socket callbacks and set sk_user_data
to an ovpn_socket instance. Currently, these two operations are
decoupled: callbacks are overridden before sk_user_data is set. While
existing callbacks perform safety checks for NULL or non-ovpn
sk_user_data, this condition causes a "half-formed" state where valid
packets arriving during attachment trigger error logs (e.g., "invoked on
non ovpn socket").
Set sk_user_data before overriding the callbacks so that it can be
accessed safely from them. Since we already check that the socket has no
sk_user_data before setting it, this remains safe even if an interrupt
accesses the socket after sk_user_data is set but before the callbacks
are overridden.
This also requires initializing all protocol-specific fields (such as
tcp_tx_work and peer links) before calling ovpn_socket_attach, ensuring
the ovpn_socket is fully formed before it becomes visible to any
callback.

On partitioned systems, multiple TPMI instances may exist per package,
but RAPL registers are only valid on one instance since RAPL has
package-scope control. Other instances return invalid versions during
domain parsing, which is expected behavior on such systems.
Currently this generates a firmware bug warning:
intel_rapl_tpmi: [Firmware Bug]: Invalid version
Remove the FW_BUG tag, downgrade to pr_debug(), and update the message
to clarify that invalid versions are expected on partitioned systems
where only one instance can be valid.

This patch introduces a count parameter to exfat_get_cluster, which
serves as an input parameter for the caller to specify the desired
number of clusters, and as an output parameter to store the length
of consecutive clusters.
This patch can improve read performance by reducing the number of
get_block calls in sequential read scenarios. speacially in small
cluster size.
According to my test data, the performance improvement is
approximately 10% when read FAT_CHAIN file with 512 bytes of
cluster size.

Change exfat_cache_lookup to return the cluster number of the last
cluster before the next cache (i.e., the end of the current cache range)
or the given 'end' if there is no next cache. This allows the caller to
know whether the next cluster after the current cache is cached.
The function signature is changed to accept an 'end' parameter, which
is the upper bound of the search range. The function now stops early
if it finds a cache that starts within the current cache's tail, meaning
caches are contiguous. The return value is the cluster number at which
the next cache starts (minus one) or the original 'end' if no next cache
is found.
The new behavior is illustrated as follows:
cache: [ccccccc-------ccccccccc]
search: [..................]
return: ^

This patch introduces a parameter 'count' to support fetching multiple
clusters in exfat_map_cluster. The returned 'count' indicates the number
of consecutive clusters, or 0 when the input cluster offset is past EOF.
And the 'count' is also an input parameter for the caller to specify the
required number of clusters.
Only NO_FAT_CHAIN files enable multi-cluster fetching in this patch.
After this patch, the time proportion of exfat_get_block has decreased,

The infinite cluster chain loop check is not work because the
loop will terminate when fclus reaches the parameter cluster,
and the parameter cluster value is never greater than
ei->valid_size.
The following relationship holds:

list, the function breaks out of the loop without cleaning up
already mapped segments. Similarly, if dma_iova_sync() fails after
linking all segments, no cleanup is performed.
This leaves partial IOVA mappings in place. The completion path
attempts to unmap the full expected size via dma_iova_destroy() or
nvme_unmap_data(), but only a partial size was actually mapped,
leading to incorrect unmap operations.
Add an out_unlink error path that calls dma_iova_destroy() to clean
up partial mappings before returning failure. The dma_iova_destroy()
function handles both partial unlink and IOVA space freeing. It
correctly handles the mapped_len == 0 case (first dma_iova_link()
failure) by only freeing the IOVA allocation without attempting to
unmap.

In io_ring_ctx_wait_and_kill(), struct creds *creds is used to
iterate and prune credentials. But the correct type is struct cred.
This doesn't matter as the variable isn't used at all, only the index
is used. But it's confusing using a type that isn't valid, so fix it
up.

Pull networking updates from Paolo Abeni:
"Core & protocols:
- A significant effort all around the stack to guide the compiler to
make the right choice when inlining code, to avoid unneeded calls
for small helper and stack canary overhead in the fast-path.
This generates better and faster code with very small or no text
size increases, as in many cases the call generated more code than
the actual inlined helper.
- Extend AccECN implementation so that is now functionally complete,
also allow the user-space enabling it on a per network namespace
basis.
- Add support for memory providers with large (above 4K) rx buffer.
Paired with hw-gro, larger rx buffer sizes reduce the number of
buffers traversing the stack, dincreasing single stream CPU usage
by up to ~30%.
- Do not add HBH header to Big TCP GSO packets. This simplifies the
RX path, the TX path and the NIC drivers, and is possible because
user-space taps can now interpret correctly such packets without
the HBH hint.
- Allow IPv6 routes to be configured with a gateway address that is
resolved out of a different interface than the one specified,
aligning IPv6 to IPv4 behavior.
- Multi-queue aware sch_cake. This makes it possible to scale the
rate shaper of sch_cake across multiple CPUs, while still enforcing
a single global rate on the interface.
- Add support for the nbcon (new buffer console) infrastructure to
netconsole, enabling lock-free, priority-based console operations
that are safer in crash scenarios.
- Improve the TCP ipv6 output path to cache the flow information,
saving cpu cycles, reducing cache line misses and stack use.
- Improve netfilter packet tracker to resolve clashes for most
protocols, avoiding unneeded drops on rare occasions.
- Add IP6IP6 tunneling acceleration to the flowtable infrastructure.
- Reduce tcp socket size by one cache line.
- Notify neighbour changes atomically, avoiding inconsistencies
between the notification sequence and the actual states sequence.
- Add vsock namespace support, allowing complete isolation of vsocks
across different network namespaces.
- Improve xsk generic performances with cache-alignment-oriented
optimizations.
- Support netconsole automatic target recovery, allowing netconsole
to reestablish targets when underlying low-level interface comes
back online.
Driver API:
- Support for switching the working mode (automatic vs manual) of a
DPLL device via netlink.
- Introduce PHY ports representation to expose multiple front-facing
media ports over a single MAC.
- Introduce "rx-polarity" and "tx-polarity" device tree properties,
to generalize polarity inversion requirements for differential
signaling.
- Add helper to create, prepare and enable managed clocks.
Device drivers:
- Add Huawei hinic3 PF etherner driver.
- Add DWMAC glue driver for Motorcomm YT6801 PCIe ethernet
controller.
- Add ethernet driver for MaxLinear MxL862xx switches
- Remove parallel-port Ethernet driver.
- Convert existing driver timestamp configuration reporting to
hwtstamp_get and remove legacy ioctl().

__io_fixed_fd_install() returns 0 on success for non-alloc mode
(specific slot), not the slot index. io_pipe_fixed() used this return
value directly as the slot index in fds[], which can cause the reported
values returned via copy_to_user() to be incorrect, or the error path
operating on the incorrect direct descriptor.
Fix by computing the actual 0-based slot index (slot - 1) for specific
slot mode, while preserving the existing behavior for auto-alloc mode
where __io_fixed_fd_install() already returns the allocated index.

pointer to the preceding Capability, to allow removal of
Capabilities that are advertised but not fully implemented (Qiang
Yu)

them, so the PCI core automatically falls back to INTx (Qiang Yu)
- Add ASPM L1.1 and L1.2 Substates context to debugfs ltssm_status

- Skip PME_Turn_Off broadcast and L2/L3 transition during suspend if
link is not up to avoid an unnecessary timeout (Manivannan
Sadhasivam)
- Revert dw-rockchip, qcom, and DWC core changes that used link-up
IRQs to trigger enumeration instead of waiting for link to be up
because the PCI core doesn't allocate bus number space for
hierarchies that might be attached (Niklas Cassel)
- Make endpoint iATU entry for MSI permanent instead of programming
it dynamically, which is slow and racy with respect to other
concurrent traffic, e.g., eDMA (Koichiro Den)
- Use iMSI-RX MSI target address when possible to fix endpoints using
32-bit MSI (Shawn Lin)
- Allow DWC host controller driver probe to continue if device is not
found or found but inactive; only fail when there's an error with
the link (Manivannan Sadhasivam)
- For controllers like NXP i.MX6QP and i.MX7D, where LTSSM registers
are not accessible after PME_Turn_Off, simply wait 10ms instead of
polling for L2/L3 Ready (Richard Zhu)
- Use multiple iATU entries to map large bridge windows and DMA

can map multiple independent inbound regions in a single BAR,
implement subrange mapping, advertise it for DWC-based Endpoints,
and add Endpoint selftests for it (Koichiro Den)
- Make resizable BARs work for Endpoint multi-PF configurations;
previously it only worked for PF 0 (Aksh Garg)
- Fix Endpoint non-PF 0 support for BAR configuration, ATU mappings,
and Address Match Mode (Aksh Garg)
- Set up iATU when ECAM is enabled; previously IO and MEM outbound
windows weren't programmed, and ECAM-related iATU entries weren't
restored after suspend/resume, so config accesses failed (Krishna
Chaitanya Chundru)
