Pull btrfs updates from David Sterba:
"New features:
- raid-stripe-tree
New tree for logical file extent mapping where the physical mapping
may not match on multiple devices. This is now used in zoned mode
to implement RAID0/RAID1* profiles, but can be used in non-zoned
mode as well. The support for RAID56 is in development and will
eventually fix the problems with the current implementation. This
is a backward incompatible feature and has to be enabled at mkfs
time.
- simple quota accounting (squota)
A simplified mode of qgroup that accounts all space on the initial
extent owners (a subvolume), the snapshots are then cheap to create
and delete. The deletion of snapshots in fully accounting qgroups
is a known CPU/IO performance bottleneck.
The squota is not suitable for the general use case but works well
for containers where the original subvolume exists for the whole
time. This is a backward incompatible feature as it needs extending
some structures, but can be enabled on an existing filesystem.
- temporary filesystem fsid (temp_fsid)
The fsid identifies a filesystem and is hard coded in the
structures, which disallows mounting the same fsid found on
different devices.
For a single device filesystem this is not strictly necessary, a
new temporary fsid can be generated on mount e.g. after a device is
cloned. This will be used by Steam Deck for root partition A/B
testing, or can be used for VM root images.
Other user visible changes:
- filesystems with partially finished metadata_uuid conversion cannot
be mounted anymore and the uuid fixup has to be done by btrfs-progs
(btrfstune).
Performance improvements:
- reduce reservations for checksum deletions (with enabled free space
tree by factor of 4), on a sample workload on file with many
extents the deletion time decreased by 12%
- make extent state merges more efficient during insertions, reduce
rb-tree iterations (run time of critical functions reduced by 5%)
Core changes:
- the integrity check functionality has been removed, this was a
debugging feature and removal does not affect other integrity
checks like checksums or tree-checker
- space reservation changes:
- more efficient delayed ref reservations, this avoids building up
too much work or overusing or exhausting the global block
reserve in some situations
- move delayed refs reservation to the transaction start time,
this prevents some ENOSPC corner cases related to exhaustion of
global reserve
- improvements in reducing excessive reservations for block group
items
- adjust overcommit logic in near full situations, account for one
more chunk to eventually allocate metadata chunk, this is mostly
relevant for small filesystems (<10GiB)
- single device filesystems are scanned but not registered (except
seed devices), this allows temp_fsid to work
- qgroup iterations do not need GFP_ATOMIC allocations anymore
- cleanups, refactoring, reduced data structure size, function
parameter simplifications, error handling fixes"

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"

Simple quotas count extents only from the moment the feature is enabled.
Therefore, if we do something like:
1. create subvol S
2. write F in S
3. enable quotas
4. remove F
5. write G in S
then after 3. and 4. we would expect the simple quota usage of S to be 0
(putting aside some metadata extents that might be written) and after
5., it should be the size of G plus metadata. Therefore, we need to be
able to determine whether a particular quota delta we are processing
predates simple quota enablement.
To do this, store the transaction id when quotas were enabled. In
fs_info for immediate use and in the quota status item to make it
recoverable on mount. When we see a delta, check if the generation of
the extent item is less than that of quota enablement. If so, we should
ignore the delta from this extent.

In order to implement simple quota groups, we need to be able to
associate a data extent with the subvolume that created it. Once you
account for reflink, this information cannot be recovered without
explicitly storing it. Options for storing it are:
- a new key/item
- a new extent inline ref item
The former is backwards compatible, but wastes space, the latter is
incompat, but is efficient in space and reuses the existing inline ref
machinery, while only abusing it a tiny amount -- specifically, the new
item is not a ref, per-se.

Sergei Trofimovich reported a regression [0] caused by commit a0ade8404c
("af_packet: Fix warning of fortified memcpy() in packet_getname().").
It introduced a flex array sll_addr_flex in struct sockaddr_ll as a
union-ed member with sll_addr to work around the fortified memcpy() check.
However, a userspace program uses a struct that has struct sockaddr_ll in
the middle, where a flex array is illegal to exist.

Report the maximum number of IBs that can be pushed with a single
DRM_IOCTL_NOUVEAU_EXEC through DRM_IOCTL_NOUVEAU_GETPARAM.
While the maximum number of IBs per ring might vary between chipsets,
the kernel will make sure that userspace can only push a fraction of the
maximum number of IBs per ring per job, such that we avoid a situation
where there's only a single job occupying the ring, which could
potentially lead to the ring run dry.
Using DRM_IOCTL_NOUVEAU_GETPARAM to report the maximum number of IBs
that can be pushed with a single DRM_IOCTL_NOUVEAU_EXEC implies that
all channels of a given device have the same ring size.

Both glibc and musl define 'struct sched_param' in sched.h, while kernel
has it in uapi/linux/sched/types.h, making it cumbersome to use
sched_getattr(2) or sched_setattr(2) from userspace.
For example, something like this:
#include <sched.h>
#include <linux/sched/types.h>
struct sched_attr sa;
will result in "error: redefinition of ‘struct sched_param’" (note the
code doesn't need sched_param at all -- it needs struct sched_attr
plus some stuff from sched.h).
The situation is, glibc is not going to provide a wrapper for
sched_{get,set}attr, thus the need to include linux/sched_types.h
directly, which leads to the above problem.
Thus, the userspace is left with a few sub-par choices when it wants to
use e.g. sched_setattr(2), such as maintaining a copy of struct
sched_attr definition, or using some other ugly tricks.
OTOH, 'struct sched_param' is well known, defined in POSIX, and it won't
be ever changed (as that would break backward compatibility).
So, while 'struct sched_param' is indeed part of the kernel uapi,
exposing it the way it's done now creates an issue, and hiding it
(like this patch does) fixes that issue, hopefully without creating
another one: common userspace software rely on libc headers, and as
for "special" software (like libc), it looks like glibc and musl
do not rely on kernel headers for 'struct sched_param' definition
(but let's Cc their mailing lists in case it's otherwise).
The alternative to this patch would be to move struct sched_attr to,
say, linux/sched.h, or linux/sched/attr.h (the new file).
Oh, and here is the previous attempt to fix the issue:
https://lore.kernel.org/all/20200528135552.GA87103@google.com/
While I support Linus arguments, the issue is still here
and needs to be fixed.
[ mingo: Linus is right, this shouldn't be needed - but on the other
hand I agree that this header is not really helpful to
user-space as-is. So let's pretend that
<uapi/linux/sched/types.h> is only about sched_attr, and
call this commit a workaround for user-space breakage
that it in reality is ... Also, remove the Fixes tag. ]

Until now, fscrypt has always used the filesystem block size as the
granularity of file contents encryption. Two scenarios have come up
where a sub-block granularity of contents encryption would be useful:
1. Inline crypto hardware that only supports a crypto data unit size
that is less than the filesystem block size.
2. Support for direct I/O at a granularity less than the filesystem
block size, for example at the block device's logical block size in
order to match the traditional direct I/O alignment requirement.
(1) first came up with older eMMC inline crypto hardware that only
supports a crypto data unit size of 512 bytes. That specific case
ultimately went away because all systems with that hardware continued
using out of tree code and never actually upgraded to the upstream
inline crypto framework. But, now it's coming back in a new way: some
current UFS controllers only support a data unit size of 4096 bytes, and
there is a proposal to increase the filesystem block size to 16K.
(2) was discussed as a "nice to have" feature, though not essential,
when support for direct I/O on encrypted files was being upstreamed.
Still, the fact that this feature has come up several times does suggest
it would be wise to have available. Therefore, this patch implements it
by using one of the reserved bytes in fscrypt_policy_v2 to allow users
to select a sub-block data unit size. Supported data unit sizes are
powers of 2 between 512 and the filesystem block size, inclusively.
Support is implemented for both the FS-layer and inline crypto cases.
This patch focuses on the basic support for sub-block data units. Some
things are out of scope for this patch but may be addressed later:
- Supporting sub-block data units in combination with
FSCRYPT_POLICY_FLAG_IV_INO_LBLK_64, in most cases. Unfortunately this
combination usually causes data unit indices to exceed 32 bits, and
thus fscrypt_supported_policy() correctly disallows it. The users who
potentially need this combination are using f2fs. To support it, f2fs
would need to provide an option to slightly reduce its max file size.
- Supporting sub-block data units in combination with
FSCRYPT_POLICY_FLAG_IV_INO_LBLK_32. This has the same problem
described above, but also it will need special code to make DUN
wraparound still happen on a FS block boundary.
- Supporting use case (2) mentioned above. The encrypted direct I/O
code will need to stop requiring and assuming FS block alignment.
This won't be hard, but it belongs in a separate patch.
- Supporting this feature on filesystems other than ext4 and f2fs.
(Filesystems declare support for it via their fscrypt_operations.)
On UBIFS, sub-block data units don't make sense because UBIFS encrypts
variable-length blocks as a result of compression. CephFS could
support it, but a bit more work would be needed to make the
fscrypt_*_block_inplace functions play nicely with sub-block data
units. I don't think there's a use case for this on CephFS anyway.

Finish off the 'simple' futex2 syscall group by adding
sys_futex_requeue(). Unlike sys_futex_{wait,wake}() its arguments are
too numerous to fit into a regular syscall. As such, use struct
futex_waitv to pass the 'source' and 'destination' futexes to the
syscall.
This syscall implements what was previously known as FUTEX_CMP_REQUEUE
and uses {val, uaddr, flags} for source and {uaddr, flags} for
destination.
This design explicitly allows requeueing between different types of
futex by having a different flags word per uaddr.

To complement sys_futex_waitv()/wake(), add sys_futex_wait(). This
syscall implements what was previously known as FUTEX_WAIT_BITSET
except it uses 'unsigned long' for the value and bitmask arguments,
takes timespec and clockid_t arguments for the absolute timeout and
uses FUTEX2 flags.
The 'unsigned long' allows FUTEX2_SIZE_U64 on 64bit platforms.

sys_futex_waitv() is part of the futex2 series (the first and only so
far) of syscalls and has a flags field per futex (as opposed to flags
being encoded in the futex op).
This new flags field has a new namespace, which unfortunately isn't
super explicit. Notably it currently takes FUTEX_32 and
FUTEX_PRIVATE_FLAG.
Introduce the FUTEX2 namespace to clarify this

__DECLARE_FLEX_ARRAY(T, member) macro expands to
struct {
struct {} __empty_member;
T member[];
};
which is subtly wrong in C++ because sizeof(struct{}) is 1 not 0,
changing UAPI structures layouts.
This can be fixed by expanding to
T member[];
Now g++ doesn't like "T member[]" either, throwing errors on
the following code:
struct S {
union {
T1 member1[];
T2 member2[];
};
};
or
struct S {
T member[];
};
Use "T member[0];" which seems to work and does the right thing wrt
structure layout.

Commit 151e887d8f ("veth: Fixing transmit return status for dropped
packets") exposed the fact that bpf_clone_redirect is capable of
returning raw NET_XMIT_XXX return codes.
This is in the conflict with its UAPI doc which says the following:
"0 on success, or a negative error in case of failure."
Update the UAPI to reflect the fact that bpf_clone_redirect can
return positive error numbers, but don't explicitly define
their meaning.

- Define NT_RISCV_CSR and re-number NT_RISCV_VECTOR to prevent

- Use struct __riscv_v_regset_state to handle ptrace requests
Since gdb does not directly include the note description header in
