Just a small cleanup while I was touching this header.
compiler_attributes.h does feature detection of these __attributes__(())
and provides more concise ways to invoke them.

__tracepoint_string's have their string data stored in .rodata, and an
address to that data stored in the "__tracepoint_str" section. Functions
that refer to those strings refer to the symbol of the address. Compiler
optimization can replace those address references with references
directly to the string data. If the address doesn't appear to have other
uses, then it appears dead to the compiler and is removed. This can
break the /tracing/printk_formats sysfs node which iterates the
addresses stored in the "__tracepoint_str" section.
Like other strings stored in custom sections in this header, mark these
__used to inform the compiler that there are other non-obvious users of
the address, so they should still be emitted.

mlx5 has the IANA VXLAN port (4789) hard coded by the device,
instead of being added dynamically when tunnels are created.
To support this add a workaround flag to struct udp_tunnel_nic_info.
Skipping updates for the port is fairly trivial, dumping the hard
coded port via ethtool requires some code duplication. The port
is not a part of any real table, we dump it in a special table
which has no tunnel types supported and only one entry.
This is the last known workaround / hack needed to convert
all drivers to the new infra.

Pull fscrypt updates from Eric Biggers:
"This release, we add support for inline encryption via the blk-crypto
framework which was added in 5.8.
Now when an ext4 or f2fs filesystem is mounted with '-o inlinecrypt',
the contents of encrypted files will be encrypted/decrypted via
blk-crypto, instead of directly using the crypto API. This model
allows taking advantage of the inline encryption hardware that is
integrated into the UFS or eMMC host controllers on most mobile SoCs.
Note that this is just an alternate implementation; the ciphertext
written to disk stays the same.
(This pull request does *not* include support for direct I/O on
encrypted files, which blk-crypto makes possible, since that part is
still being discussed.)
Besides the above feature update, there are also a few fixes and
cleanups, e.g. strengthening some memory barriers that may be too
weak.
All these patches have been in linux-next with no reported issues.
I've also tested them with the fscrypt xfstests, as usual. It's also
been tested that the inline encryption support works with the support
for Qualcomm and Mediatek inline encryption hardware that will be in
the scsi pull request for 5.9. Also, several SoC vendors are already
using a previous, functionally equivalent version of these patches"

Pull btrfs updates from David Sterba:
"We don't have any big feature updates this time, there are lots of
small enhacements or fixes. A highlight perhaps is the parallel fsync
performance improvements, numbers below.
Regarding the dio/iomap that was reverted last time, the required API
changes are likely to land in the upcoming cycle, the btrfs part will
be updated afterwards.
User visible changes:
- new mount option rescue= to group all recovery-related mount
options so we don't have many specific options, currently
introducing only aliases for existing options, future extensions
are in development to allow read-only mount with partially damaged
structures:
- usebackuproot is an alias for rescue=usebackuproot
- nologreplay is an alias for rescue=nologreplay
- start deprecation of mount option inode_cache, removal scheduled to
v5.11
- removed deprecated mount options alloc_start and subvolrootid
- device stats corruption counter gets incremented when a checksum
mismatch is found
- qgroup information exported in /sys/fs/btrfs/<UUID>/qgroups/<id>
using sysfs
- add link /sys/fs/btrfs/<UUID>/bdi pointing to the associated
backing dev info
- FS_INFO ioctl enhancements:
- add flags to request/describe newly added items
- new item: numeric checksum type and checksum size
- new item: generation
- new item: metadata_uuid
- seed device: with one new read-write device added, print the new
device information in /proc/mounts
- balance: detect cancellation by Ctrl-C in existing cancellation
points
Performance improvements:
- optimized versions of various helpers on little-endian
architectures, where we don't have to do LE/BE conversion from
on-disk format
- tree-log/fsync optimizations leading to lower max latency reported
by dbench, reduced by about 12%
- all chunk tree leaves are prefetched at mount time, can improve
mount time on large (terabyte-sized) filesystems
- speed up parallel fsync of files with reflinked/deduped extents,
with jobs 16 to 1024 the throughput gets improved roughly by 50% on
average and runtime decreased roughly by 30% on average, notable
outlier is 128 jobs with +121.2% on throughput and -54.6% runtime
- another speed up of parallel fsync, reduce number of checksum tree
lookups and contention, the improvements start to show up with 2
tasks with +20% throughput and -16% runtime up to 64 with +200%
throughput and -66% runtime
Core:
- umount-time qgroup leak checker
- qgroups
- add a way to unreserve partial range after failure, avoiding
some EDQUOT errors
- improved flushing logic when EDQUOT is hit
- possible EINTR interruption caused by failed reservations after
transaction start is better handled and documented
- transaction abort errors are unified to EROFS in case it's not the
original reason of abort or we don't have other way to determine
the reason
Fixes:
- make truncate succeed on a NOCOW file even if data space is
exhausted
- fix cancelling balance on filesystem with exhausted metadata space
- anon block device:
- preallocate anon bdev when subvolume is created to report
failure early
- shorten time the anon bdev id is allocated
- don't allocate anon bdev for internal roots
- minor memory leak in ref-verify
- refuse invalid combinations of compression and NOCOW file flags
- lockdep fixes, updating the device locks
- remove obsolete fallback logic for block group profile adjustments
when switching from 1 to more devices, causing allocation of
unwanted block groups
Other cleanups, refactoring, simplifications:
- conversions from struct inode to struct btrfs_inode in internal
functions
- removal of unused struct members"

ASoC: Updates for v5.9
The biggest changes here one again come from Mormioto-san who has
continued his dilligent work cleaning up long standing issues in the
APIs, it's particularly nice to see the transition from digital_mute()
to mute_stream() finally completed. There's also been a lot of work on
the x86 code again, this time a big focus has been on cleaning up some
issues identified by various static tests, and on the Freescale systems.
Otherwise the biggest thing has been a lot of driver additions:
- Convert users of digital_mute() to mute_stream().
- Simplify I/O helper functions.
- Add a helper for getting the RTD from a substream.
- Many, many fixes and cleanups to the x86 code.
- New drivers for Freescale MQS and i.MX6sx, Intel KeemBay I2S, Maxim
MAX98360A and MAX98373 Soundwire, several Mediatek boards, nVidia
Tegra 186 and 210, RealTek RL6231, Samsung Midas and Aries boards (some
of the first phones I worked on!) and TI J721e EVM.

Multicolor is a bit too abstract. Yes, we can have
Green-Magenta-Ultraviolet LED, but so far all the LEDs we support are
RGB, and not even RGB-White or RGB-Yellow variants emerged.
Multicolor is not a good fit for RGB LED. It does not really know
about LED color. In particular, there's no way to make LED "white".
Userspace is interested in knowing "this LED can produce arbitrary
color", which not all multicolor LEDs can.

SAE authentication has been extended with H2E (IEEE 802.11 REVmd) and PK
(WFA) options. Those extensions use special status code values in the
SAE commit messages (Authentication frame with transaction sequence
number 1) to identify which extension is in use. mac80211 was
interpreting those new values as the AP denying authentication and that
resulted in failure to complete SAE authentication in some cases.
Fix this by adding exceptions for the new status code values 126 and
127.

Add LINK_DETACH command to force-detach bpf_link without destroying it. It has
the same behavior as auto-detaching of bpf_link due to cgroup dying for
bpf_cgroup_link or net_device being destroyed for bpf_xdp_link. In such case,
bpf_link is still a valid kernel object, but is defuncts and doesn't hold BPF
program attached to corresponding BPF hook. This functionality allows users
with enough access rights to manually force-detach attached bpf_link without
killing respective owner process.
This patch implements LINK_DETACH for cgroup, xdp, and netns links, mostly
re-using existing link release handling code.

Use a local var to collect flags in kiocb_set_rw_flags(). That spares
some memory writes and allows to replace most of the jumps with MOVEcc.

netdev protodown is a mechanism that allows protocols to
hold an interface down. It was initially introduced in
the kernel to hold links down by a multihoming protocol.
There was also an attempt to introduce protodown
reason at the time but was rejected. protodown and protodown reason
is supported by almost every switching and routing platform.
It was ok for a while to live without a protodown reason.
But, its become more critical now given more than
one protocol may need to keep a link down on a system
at the same time. eg: vrrp peer node, port security,
multihoming protocol. Its common for Network operators and
protocol developers to look for such a reason on a networking
box (Its also known as errDisable by most networking operators)
This patch adds support for link protodown reason
attribute. There are two ways to maintain protodown
reasons.
(a) enumerate every possible reason code in kernel
- A protocol developer has to make a request and
have that appear in a certain kernel version
(b) provide the bits in the kernel, and allow user-space
(sysadmin or NOS distributions) to manage the bit-to-reasonname
map.
- This makes extending reason codes easier (kind of like
the iproute2 table to vrf-name map /etc/iproute2/rt_tables.d/)
This patch takes approach (b).
a few things about the patch:
- It treats the protodown reason bits as counter to indicate
active protodown users
- Since protodown attribute is already an exposed UAPI,
the reason is not enforced on a protodown set. Its a no-op
if not used.
the patch follows the below algorithm:
- presence of reason bits set indicates protodown
is in use
- user can set protodown and protodown reason in a
single or multiple setlink operations
- setlink operation to clear protodown, will return -EBUSY
if there are active protodown reason bits
- reason is not included in link dumps if not used
example with patched iproute2:
$cat /etc/iproute2/protodown_reasons.d/r.conf
0 mlag
1 evpn
2 vrrp
3 psecurity
$ip link set dev vxlan0 protodown on protodown_reason vrrp on
$ip link set dev vxlan0 protodown_reason mlag on
$ip link show
14: vxlan0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode
DEFAULT group default qlen 1000
link/ether f6:06:be:17:91:e7 brd ff:ff:ff:ff:ff:ff protodown on <mlag,vrrp>
$ip link set dev vxlan0 protodown_reason mlag off
$ip link set dev vxlan0 protodown off protodown_reason vrrp off

3) Fix crash when the hold queue is used. The assumption that
xdst->path and dst->child are not a NULL pointer only if dst->xfrm
is not a NULL pointer is true with the exception of using the
hold queue. Fix this by checking for hold queue usage before
dereferencing xdst->path or dst->child.

This change adds TCP_NLA_EDT to SCM_TIMESTAMPING_OPT_STATS that reports
the earliest departure time(EDT) of the timestamped skb. By tracking EDT
values of the skb from different timestamps, we can observe when and how
much the value changed. This allows to measure the precise delay
injected on the sender host e.g. by a bpf-base throttler.

If SYN packet contains MP_CAPABLE option, keep it enabled.
Syncokie validation and cookie-based socket creation is changed to
instantiate an mptcp request sockets if the ACK contains an MPTCP
connection request.
Rather than extend both cookie_v4/6_check, add a common helper to create
the (mp)tcp request socket.

Will be used to initialize the mptcp request socket when a MP_CAPABLE
request was handled in syncookie mode, i.e. when a TCP ACK containing a
MP_CAPABLE option is a valid syncookie value.
Normally (non-cookie case), MPTCP will generate a unique 32 bit connection
ID and stores it in the MPTCP token storage to be able to retrieve the
mptcp socket for subflow joining.
In syncookie case, we do not want to store any state, so just generate the
unique ID and use it in the reply.
This means there is a small window where another connection could generate
the same token.
When Cookie ACK comes back, we check that the token has not been registered
in the mean time. If it was, the connection needs to fall back to TCP.
Changes in v2:
- use req->syncookie instead of passing 'want_cookie' arg to ->init_req()
