This patch adds an xrun counter to snd_pcm_substream as an alternative
to using logs from XRUN_DEBUG_BASIC. The counter provides a way to track
the number of xrun occurences, accessible through the /proc interface.
The counter is enabled when CONFIG_SND_PCM_XRUN_DEBUG is set.
Example output:
$ cat /proc/asound/card0/pcm9p/sub0/status

Devices can provide multiple interrupt lines. One reason for this is that
a device has multiple subfunctions, each providing its own interrupt line.
Another reason is that a device can be designed to be used (also) on a
system where some of the interrupts can be routed to another processor.
A line often further acts as a demultiplex for specific interrupts
and has it's respective set of interrupt (status, mask, ack, ...)
registers.
Regmap supports the handling of these registers and demultiplexing
interrupts, but the interrupt domain code ends up assigning the same name
for the per interrupt line domains. This causes a naming collision in the
debugFS code and leads to confusion, as /proc/interrupts shows two separate
interrupts with the same domain name and hardware interrupt number.
Instead of adding a workaround in regmap or driver code, allow giving a
name suffix for the domain name when the domain is created.
Add a name_suffix field in the irq_domain_info structure and make
irq_domain_instantiate() use this suffix if it is given when a domain is
created.

irq_domain_create_simple() and irq_domain_create_legacy() use
__irq_domain_instantiate(), but have extra handling of allocating interrupt
descriptors and associating interrupts in them. Some of that is duplicated.
There are also call sites which have conditonals to invoke different
interrupt domain creator functions, where one of them is usually
irq_domain_create_legacy(). Alternatively they associate the interrupts for
the legacy case after creating the domain.
Moving the extra logic of irq_domain_create_simple()/legacy() into
__irq_domain_instantiate() allows to consolidate that.
Introduce hwirq_base and virq_base members in the irq_domain_info
structure, which allows to transport the required information and add the
conditional interrupt descriptor allocation and interrupt association into
__irq_domain_instantiate().
This reduces irq_domain_create_legacy() and irq_domain_create_simple() to
trivial wrappers which fill in the info structure and allows call sites
which must support the legacy case along with more modern mechanism to
select the domain type via the parameters of the info struct.

The recent cleanup in ALSA control core made no difference between
snd_ctl_find_id_mixer() and snd_ctl_find_id_mixer_locked(), and the
latter is to be dropped. The only user of the left API was ASoC, and
that's snd_soc_card_get_kcontrol_locked() and
snd_soc_component_get_kcontrol_locked().
This patch drops those functions and rewrites those users to call the
variant without locked instead. The test of the API became
superfluous, hence dropped as well.
As all callers of snd_ctl_find_id_mixer_locked() are gone,
snd_ctl_find_id_mixer_locked() is finally dropped, too.

For a fast look-up of a control element via either numid or name
matching (enabled via CONFIG_SND_CTL_FAST_LOOKUP), a locking isn't
needed at all thanks to Xarray. OTOH, the locking is still needed for
a slow linked-list traversal, and that's rather a rare case.
In this patch, we reduce the use of locking at snd_ctl_find_*() API
functions, and switch from controls_rwsem to controls_rwlock for
avoiding unnecessary lock inversions. This also resulted in a nice
cleanup, as *_unlocked() version of snd_ctl_find_*() APIs can be
dropped.
snd_ctl_find_id_mixer_unlocked() is still left just as an alias of
snd_ctl_find_id_mixer(), since soc-card.c has a wrapper and there are
several users. Once after converting there, we can remove it later.

Christian Brauner <brauner@kernel.org> says:
Recently, we added the ability to list mounts in other mount namespaces
and the ability to retrieve namespace file descriptors without having to
go through procfs by deriving them from pidfds.
This extends nsfs in two ways:
(1) Add the ability to retrieve information about a mount namespace via
NS_MNT_GET_INFO. This will return the mount namespace id and the
number of mounts currently in the mount namespace. The number of
mounts can be used to size the buffer that needs to be used for
listmount() and is in general useful without having to actually
iterate through all the mounts.
The structure is extensible.
(2) Add the ability to iterate through all mount namespaces over which
the caller holds privilege returning the file descriptor for the
next or previous mount namespace.
To retrieve a mount namespace the caller must be privileged wrt to
it's owning user namespace. This means that PID 1 on the host can
list all mounts in all mount namespaces or that a container can list
all mounts of its nested containers.
Optionally pass a structure for NS_MNT_GET_INFO with
NS_MNT_GET_{PREV,NEXT} to retrieve information about the mount
namespace in one go.
(1) and (2) can be implemented for other namespace types easily.
Together with recent api additions this means one can iterate through
all mounts in all mount namespaces without ever touching procfs. Here's

Currently the only opportunity to set sock ops flags dictating
which callbacks fire for a socket is from within a TCP-BPF sockops
program. This is problematic if the connection is already set up
as there is no further chance to specify callbacks for that socket.
Add TCP_BPF_SOCK_OPS_CB_FLAGS to bpf_setsockopt() and bpf_getsockopt()
to allow users to specify callbacks later, either via an iterator
over sockets or via a socket-specific program triggered by a
setsockopt() on the socket.
Previous discussion on this here [1].

Merge series from Linus Walleij <linus.walleij@linaro.org>:
The TI TAS drivers use some legacy GPIO code and headers,
this series fixes it up.
The TAS2781 is a special case since it adds a handful of
lines of deviating code to reconfigure a GPIO line for
IRQ mode and then never actually use the IRQ obtained in
the code. Is the line used by autonomous hardware? I'm
puzzled by this.
Anyways the patch suggest how to solve this properly by
fixing the parent irqchip and I'm happy to help.

Both ethtool_ops.rxfh_max_context_id and the default value used when
it's not specified are supposed to be exclusive maxima (the former
is documented as such; the latter, U32_MAX, cannot be used as an ID
since it equals ETH_RXFH_CONTEXT_ALLOC), but xa_alloc() expects an
inclusive maximum.
Subtract one from 'limit' to produce an inclusive maximum, and pass
that to xa_alloc().
Increase bnxt's max by one to prevent a (very minor) regression, as
BNXT_MAX_ETH_RSS_CTX is an inclusive max. This is safe since bnxt
is not actually hard-limited; BNXT_MAX_ETH_RSS_CTX is just a
leftover from old driver code that managed context IDs itself.
Rename rxfh_max_context_id to rxfh_max_num_contexts to make its
semantics (hopefully) more obvious.

The numbering in Exynos7885's FSYS CMU bindings has 4 duplicated by
accident, with the rest of the bindings continuing with 5.
Fix this by moving CLK_MOUT_FSYS_USB30DRD_USER to the end as 11.
Since CLK_MOUT_FSYS_USB30DRD_USER is not used in any device tree as of
now, and there are no other clocks affected (maybe apart from
CLK_MOUT_FSYS_MMC_SDIO_USER which the number was shared with, also not
used in a device tree), this is the least impactful way to solve this
problem.

The tas2781-i2c driver gets an IRQ from either ACPI or device tree,
then proceeds to check if the IRQ has a corresponding GPIO and in
case it does enforce the GPIO as input and set a label on it.
This is abuse of the API:
- First we cannot guarantee that the numberspaces of the GPIOs and
the IRQs are the same, i.e that an IRQ number corresponds to
a GPIO number like that.
- Second, GPIO chips and IRQ chips should be treated as orthogonal
APIs, the irqchip needs to ascertain that the backing GPIO line
is set to input etc just using the irqchip.
- Third it is using the legacy <linux/gpio.h> API which should not
be used in new code yet this was added just a year ago.
Delete the offending code.
If this creates problems the GPIO and irqchip maintainers can help
to fix the issues.
It *should* not create any problems, because the irq isn't
used anywhere in the driver, it's just obtained and then
left unused.
