Use min() to simplify snd_hda_get_devices() and improve its readability.
Change the function parameter 'max_devices' from 'int' to 'unsigned int'
to avoid a min() signedness error. Update all related local variables
and the function's return type to 'unsigned int' accordingly.
No functional changes intended.

syzbot found a race condition when kcm_unattach(psock)
and kcm_release(kcm) are executed at the same time.
kcm_unattach() is missing a check of the flag
kcm->tx_stopped before calling queue_work().
If the kcm has a reserved psock, kcm_unattach() might get executed
between cancel_work_sync() and unreserve_psock() in kcm_release(),
requeuing kcm->tx_work right before kcm gets freed in kcm_done().
Remove kcm->tx_stopped and replace it by the less
error-prone disable_work_sync().

In the past %pK was preferable to %p as it would not leak raw pointer
values into the kernel log.
Since commit ad67b74d2469 ("printk: hash addresses printed with %p")
the regular %p has been improved to avoid this issue.
Furthermore, restricted pointers ("%pK") were never meant to be used
through printk(). They can still unintentionally leak raw pointers or
acquire sleeping locks in atomic contexts.
Switch to the regular pointer formatting which is safer and
easier to reason about.

The CS_ONLINE flag was introduced prior to the CSS_ONLINE flag in the
cpuset subsystem. Currently, the flag setting sequence is as follows:
1. cpuset_css_online() sets CS_ONLINE
2. css->flags gets CSS_ONLINE set
...
3. cgroup->kill_css sets CSS_DYING
4. cpuset_css_offline() clears CS_ONLINE
5. css->flags clears CSS_ONLINE
The is_cpuset_online() check currently occurs between steps 1 and 3.
However, it would be equally safe to perform this check between steps 2
and 3, as CSS_ONLINE provides the same synchronization guarantee as
CS_ONLINE.
Since CS_ONLINE is redundant with CSS_ONLINE and provides no additional
synchronization benefits, we can safely remove it to simplify the code.

kcov_remote_start_usb_softirq() the begin of urb's completion callback.
HCDs marked HCD_BH will invoke this function from the softirq and
in_serving_softirq() will detect this properly.
Root-HUB (RH) requests will not be delayed to softirq but complete
immediately in IRQ context.
This will confuse kcov because in_serving_softirq() will report true if
the softirq is served after the hardirq and if the softirq got
interrupted by the hardirq in which currently runs.
This was addressed by simply disabling interrupts in
kcov_remote_start_usb_softirq() which avoided the interruption by the RH
while a regular completion callback was invoked.
This not only changes the behaviour while kconv is enabled but also
breaks PREEMPT_RT because now sleeping locks can no longer be acquired.
Revert the previous fix. Address the issue by invoking
kcov_remote_start_usb() only if the context is just "serving softirqs"
which is identified by checking in_serving_softirq() and in_hardirq()
must be false.

Introduce a helper for v4l2 sensor drivers on both DT- and ACPI-based
platforms to retrieve a reference to the clock producer from firmware.
This helper behaves the same as devm_clk_get() except where there is
no clock producer like in ACPI-based platforms.
For ACPI-based platforms the function will read the "clock-frequency"
ACPI _DSD property and register a fixed frequency clock with the frequency
indicated in the property.
This function also handles the special ACPI-based system case where:
. The clock-frequency _DSD property is present.
. A reference to the clock producer is present, where the clock is provided
by a camera sensor PMIC driver (e.g. int3472/tps68470.c)
In this case try to set the clock-frequency value to the provided clock.

Enable user-space to inject an event into a CM through it's event
channel. Two new events are added and supported: RDMA_CM_EVENT_USER and
RDMA_CM_EVENT_INTERNAL. With these 2 events a new event parameter "arg"
is supported, which is passed from sender to receiver transparently.
With this feature an application is able to write an event into a CM
channel with a new user-space rdmacm API. For example thread T1 could
write an event with the API:
rdma_write_cm_event(cm_id, RDMA_CM_EVENT_USER, status, arg);
and thread T2 could receive the event with rdma_get_cm_event().

Add new UCMA command and the corresponding CMA implementation. Userspace
can send this command to request service resolution based on service
name or ID.
On a successful resolution, one or multiple service records are
returned, the first one will be used as destination address by default.
Two new CM events are added and returned to caller accordingly:
- RDMA_CM_EVENT_ADDRINFO_RESOLVED: Resolve succeeded;
- RDMA_CM_EVENT_ADDRINFO_ERROR: Resolve failed.
Internally two new CM states are added:
- RDMA_CM_ADDRINFO_QUERY: CM is in the process of IB service
resolution;
- RDMA_CM_ADDRINFO_RESOLVED: CM has finished the resolve process.
With these new states, beside existing state transfer processes, 2 new
processes are supported:
1. The default address is used:
RDMA_CM_ADDR_BOUND ->
RDMA_CM_ADDRINFO_QUERY ->
RDMA_CM_ADDRINFO_RESOLVED ->
RDMA_CM_ROUTE_QUERY
2. To use a different address:
RDMA_CM_ADDR_BOUND ->
RDMA_CM_ADDRINFO_QUERY->
RDMA_CM_ADDRINFO_RESOLVED ->
RDMA_CM_ADDR_QUERY ->
RDMA_CM_ADDR_RESOLVED ->
RDMA_CM_ROUTE_QUERY
In the 2nd case, resolve_addrinfo returns multiple records, a user
could call rdma_resolve_addr() with the one that is not the first.

The __clear_task_blocked_on() helper added a number of sanity
checks ensuring we hold the mutex wait lock and that the task
we are clearing blocked_on pointer (if set) matches the mutex.
However, there is an edge case in the _ww_mutex_wound() logic
where we need to clear the blocked_on pointer for the task that
owns the mutex, not the task that is waiting on the mutex.
For this case the sanity checks aren't valid, so handle this
by allowing a NULL lock to skip the additional checks.
K Prateek Nayak and Maarten Lankhorst also pointed out that in
this case where we don't hold the owner's mutex wait_lock, we
need to be a bit more careful using READ_ONCE/WRITE_ONCE in both
the __clear_task_blocked_on() and __set_task_blocked_on()
implementations to avoid accidentally tripping WARN_ONs if two
instances race. So do that here as well.
This issue was easier to miss, I realized, as the test-ww_mutex
driver only exercises the wait-die class of ww_mutexes. I've
sent a patch[1] to address this so the logic will be easier to
test.

Now that all drivers access the v4l2_fh from the file structure, there
is no need to pass it as an explicit argument to ioctl handlers. Set the
argument to NULL in the __video_do_ioctl() function, and rename the 'fh'
argument in the ioctl handler declarations to 'priv' indicate it does
not contain a file handle.
The argument could be removed altogether with a mechanical change
(probably using coccinelle), but there are plans to pass a new argument
to the ioctl handlers in the near future. The tree-wide change to remove
the argument, only to add another one soon after, would be too much
churn.

Yonghong noticed that error messages for potential verifier bugs often
have a '(1)' at the end. This is happening because verifier_bug_if(cond,

verifier_bug() is defined as:
#define verifier_bug(env, fmt, args...) verifier_bug_if(1, env, fmt, ##args)
Hence, verifier_bug() always ends up displaying '(1)'. This small patch
fixes it by having verifier_bug_if conditionally call verifier_bug
instead of the other way around.

Currently when adding devlink port, phys_port_name is automatically
generated within devlink port initialization flow. As a result adding
devlink port support to driver may result in forced changes of interface
names, which breaks already existing network configs.
This is an expected behavior but in some scenarios it would not be
preferable to provide such limitation for legacy driver not being able to
keep 'pre-devlink' interface name.
Add flag no_phys_port_name to devlink_port_attrs struct which indicates
if devlink should not alter name of interface.

When dlm_lockspace_release() is passed DLM_RELEASE_RECOVER, it
tells the dlm to handle the release/leave as if the node had failed,
i.e. perform recovery steps for a failed node, like recover_slot().
When DLM_RELEASE_RECOVER is set:
- dlm_release_lockspace() includes RELEASE_RECOVER=1 in the OFFLINE
uevent sent to userspace.
- userspace/dlm_controld sends a message to all lockspace members
indicating that the subsequent node removal should be handled as
if the node had failed.
- when dlm_controld on all nodes receives the new message, it sets
the release_recover configfs entry to 1 for the node.
- when the dlm/kernel next performs recovery and removes the node,
it will see that release_recover has been set, and will perform
recovery steps for the node as if it had failed, e.g. the
recover_slot() callback is called to notify the fs.

Merge series from Cezary Rojewski <cezary.rojewski@intel.com>:
The code presented here is a lighter version of what was initially
discussed in 2021 [1]. Later, we've had a more general discussion [2]
"what if the feature was part of the ASoC core instead?". The discussion
turned towards leaving a simplified version within the avs/, so here is
the final outcome.
What's removed when compared to the older [1] version?
- conditional path priorities
- conditional path overriding
The background:
Conditional path (condpath) helps facilitate modern audio usecases such
as Echo Cancellations and Noise Reduction. These are not invoked by the
means of userspace application opening an endpoint (FrontEnd) but are a
"side effect" of selected PCMs running simultaneously e.g.: if both
Speaker (source) and Microphone Array (sink) are running, reference
data from the Speaker and take it into account when processing capture
for better voice command detection ratio.
Which PCMs are needed for given conditional path to be spawned is
determinated by the driver when registering the condpath.
Two patches implement the feature:
1) update the topology parser to acknowledge the new tuples
2) update the path-creation and functions that participate in the
PCM-runtime e.g.: run/pause.
The runtime update is needed to keep streaming sane - all the path
operations shall be synchronized when a condpath is being spawned or its
status is about to change.

We have to make sure that all future NAPIs will have the right threaded
state when the state is configured on the device level.
We chose not to have an "unset" state for threaded, and not to wipe
the NAPI config clean when channels are explicitly disabled.
This means the persistent config structs "exist" even when their NAPIs
are not instantiated.
Differently put - the NAPI persistent state lives in the net_device
(ncfg == struct napi_config):
,--- [napi 0] - [napi 1]
[dev] | |
`--- [ncfg 0] - [ncfg 1]
so say we a device with 2 queues but only 1 enabled:
,--- [napi 0]
[dev] |
`--- [ncfg 0] - [ncfg 1]
now we set the device to threaded=1:
,---------- [napi 0 (thr:1)]
[dev(thr:1)] |
`---------- [ncfg 0 (thr:1)] - [ncfg 1 (thr:?)]
Since [ncfg 1] was not attached to a NAPI during configuration we
skipped it. If we create a NAPI for it later it will have the old
setting (presumably disabled). One could argue if this is right
or not "in principle", but it's definitely not how things worked
before per-NAPI config..

sub-system, allow it to be recorded regardless of the existence of any

To test, install and run the fapolicyd daemon with default config. Then
as an unprivileged user, create and run a very simple binary that should
be denied. Then check for an event with

The current iosys_map_clear() implementation reads the potentially
uninitialized 'is_iomem' boolean field to decide which union member
to clear. This causes undefined behavior when called on uninitialized
structures, as 'is_iomem' may contain garbage values like 0xFF.
UBSAN detects this as:
UBSAN: invalid-load in include/linux/iosys-map.h:267
load of value 255 is not a valid value for type '_Bool'
Fix by unconditionally clearing the entire structure with memset(),
eliminating the need to read uninitialized data and ensuring all
fields are set to known good values.

Christoph suggested that the explicit _GPL_ can be dropped from the
module namespace export macro, as it's intended for in-tree modules
only. It would be possible to restrict it technically, but it was
pointed out [2] that some cases of using an out-of-tree build of an
in-tree module with the same name are legitimate. But in that case those
also have to be GPL anyway so it's unnecessary to spell it out in the
macro name.
