"Here's the bcachefs filesystem pull request.

One new patch since last week: the exportfs constants ended up
conflicting with other filesystems that are also getting added to the
global enum, so switched to new constants picked by Amir.

The only new non fs/bcachefs/ patch is the objtool patch that adds
bcachefs functions to the list of noreturns. The patch that exports
osq_lock() has been dropped for now, per Ingo"

Merge tag 'nfsd-6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/cel/linux

Pull nfsd updates from Chuck Lever:
"This release completes the SunRPC thread scheduler work that was begun
in v6.6. The scheduler can now find an svc thread to wake in constant
time and without a list walk. Thanks again to Neil Brown for this
overhaul.

Lorenzo Bianconi contributed infrastructure for a netlink-based NFSD
control plane. The long-term plan is to provide the same functionality
as found in /proc/fs/nfsd, plus some interesting additions, and then
migrate the NFSD user space utilities to netlink.

A long series to overhaul NFSD's NFSv4 operation encoding was applied
in this release. The goals are to bring this family of encoding
functions in line with the matching NFSv4 decoding functions and with
the NFSv2 and NFSv3 XDR functions, preparing the way for better memory
safety and maintainability.

A further improvement to NFSD's write delegation support was
contributed by Dai Ngo. This adds a CB_GETATTR callback, enabling the
server to retrieve cached size and mtime data from clients holding
write delegations. If the server can retrieve this information, it
does not have to recall the delegation in some cases.

The usual panoply of bug fixes and minor improvements round out this
release. As always I am grateful to all contributors, reviewers, and
testers"

acpi: Move common tables helper functions to common lib

Some of the routines in ACPI driver/acpi/tables.c can be shared with
parsing CDAT. CDAT is a device-provided data structure that is formatted
similar to a platform provided ACPI table. CDAT is used by CXL and can
exist on platforms that do not use ACPI. Split out the common routine
from ACPI to accommodate platforms that do not support ACPI and move that
to /lib. The common routines can be built outside of ACPI if
FIRMWARE_TABLES is selected.

lib: objpool test module added

The test_objpool module (test_objpool) will run several testcases
for objpool stress and performance evaluation. Each testcase will
have all available cpu cores involved to create a situation of high
parallel and high contention.

As of now there are 5 groups and 5 * 2 testcases in total:

1) group 1: synchronous mode
objpool is managed synchronously, that is, all objects are to be
reclaimed before objpool finalization and the objpool owner makes
sure of it. All threads on different cores run in the same pace
2) group 2: synchronous mode + hrtimer
this case have 2 customers: normal threads and hrtimer softirqs
3) group 3: synchronous + overrun mode
This test group is mainly for performance evaluation of missing
cases when pre-allocated objects are less than the requested
4) group 4: asynchronous mode
This case is just an emulation of kretprobe, with refcount used
to control the objpool lifecycle
5) group 5: asynchronous mode with hrtimer
hrtimer softirq is introduced to stress async objpool operations

lib: objpool added: ring-array based lockless MPMC

objpool is a scalable implementation of high performance queue for
object allocation and reclamation, such as kretprobe instances.

With leveraging percpu ring-array to mitigate hot spots of memory
contention, it delivers near-linear scalability for high parallel
scenarios. The objpool is best suited for the following cases:
1) Memory allocation or reclamation are prohibited or too expensive
2) Consumers are of different priorities, such as irqs and threads

Limitations:
1) Maximum objects (capacity) is fixed after objpool creation
2) All pre-allocated objects are managed in percpu ring array,
which consumes more memory than linked lists

lib: add light-weight queuing mechanism.

lwq is a FIFO single-linked queue that only requires a spinlock
for dequeueing, which happens in process context. Enqueueing is atomic
with no spinlock and can happen in any context.

This is particularly useful when work items are queued from BH or IRQ
context, and when they are handled one at a time by dedicated threads.

Avoiding any locking when enqueueing means there is no need to disable
BH or interrupts, which is generally best avoided (particularly when
there are any RT tasks on the machine).

This solution is superior to using "list_head" links because we need
half as many pointers in the data structures, and because list_head
lists would need locking to add items to the queue.

This solution is superior to a bespoke solution as all locking and
container_of casting is integrated, so the interface is simple.

Despite the similar name, this solution meets a distinctly different
need to kfifo. kfifo provides a fixed sized circular buffer to which
data can be added at one end and removed at the other, and does not
provide any locking. lwq does not have any size limit and works with
data structures (objects?) rather than data (bytes).

A unit test for basic functionality, which runs at boot time, is included.

lib/bitmap: split-out string-related operations to a separate files

lib/bitmap.c and corresponding include/linux/bitmap.h are intended to
hold functions related to operations on bitmaps, like bitmap_shift or
bitmap_set. Historically, some string-related operations like
bitmap_parse are also reside in lib/bitmap.c.

Now that the subsystem evolves, string-related bitmap operations became a
significant part of the file. Because they are quite different from the
other bitmap functions by nature, it's worth to split them to a separate
source/header files.
