Commit 7175e131ebba ("fs: dlm: fix invalid derefence of sb_lvbptr")
fixes an issue when the lkb->lkb_lvbptr set to an dangled pointer and an
followed memcpy() would fail. It was fixed by an additional check of
DLM_LKF_VALBLK flag. The mentioned commit forgot to add an additional check
if DLM_LKF_VALBLK is set for the additional amount of LVB data allocated
in a dlm message. This patch is changing the message allocation to check
additionally if DLM_LKF_VALBLK is set otherwise a dangled lkb->lkb_lvbptr
pointer would allocated zero LVB message data which not gets filled with
actual data.
This patch is however only a cleanup to reduce the amount of zero bytes
transmitted over network as receive_lvb() will only evaluates message LVB
data if DLM_LKF_VALBLK is set.

It seems there is a misprint in the check of strdup() return code that
can lead to NULL pointer dereference.

Add trace_iomap_dio_rw_begin, trace_iomap_dio_rw_queued and
trace_iomap_dio_complete tracepoint.
trace_iomap_dio_rw_queued is mostly only to know that the request was
queued and -EIOCBQUEUED was returned. It is mostly trace_iomap_dio_rw_begin
& trace_iomap_dio_complete which has all the details.

IOMAP_DIO_NOSYNC earlier was added for use in btrfs. But it seems for
aio dsync writes this is not useful anyway. For aio dsync case, we
we queue the request and return -EIOCBQUEUED. Now, since IOMAP_DIO_NOSYNC
doesn't let iomap_dio_complete() to call generic_write_sync(),
hence we may lose the sync write.
Hence kill this flag as it is not in use by any FS now.

When an error occurs during USB disconnection sometimes things can go
wrong as endpoint_set_interface may end up being called repeatedly. For
example:
% dmesg --notime | grep 'usb 3-7.1.4' | sort | uniq -c | head -2
3069 usb 3-7.1.4: 1:1: usb_set_interface failed (-19)
908 usb 3-7.1.4: 1:1: usb_set_interface failed (-71)
In my case, there sometimes are hundreds of these usb_set_interface
failure messages a second when I disconnect the hub that has my USB
audio device.
These messages can take a huge amount of the kmsg ringbuffer and don't
provide any extra information over the previous ones, so ratelimit them.

When calculating the address of the refcount_t struct within a local
kptr, bpf_refcount_acquire_impl should add refcount_off bytes to the
address of the local kptr. Due to some missing parens, the function is
incorrectly adding sizeof(refcount_t) * refcount_off bytes. This patch
fixes the calculation.
Due to the incorrect calculation, bpf_refcount_acquire_impl was trying
to refcount_inc some memory well past the end of local kptrs, resulting
in kasan and refcount complaints, as reported in [0]. In that thread,
Florian and Eduard discovered that bpf selftests written in the new
style - with __success and an expected __retval, specifically - were
not actually being run. As a result, selftests added in bpf_refcount
series weren't really exercising this behavior, and thus didn't unearth
the bug.
With this fixed behavior it's safe to revert commit 7c4b96c00043
("selftests/bpf: disable program test run for progs/refcounted_kptr.c"),
this patch does so.

This happens since btf->refcount can be 1 at the time of btf_put() and
btf_put() will call btf_free_id() which will try to grab btf_idr_lock
and will dead lock.
Avoid the issue by doing btf_put() without locking.

The bit flags in pmbus_driver_info functionality for YM-2151E chip were
joined with a comma operator instead of a bitwise OR. This means that
the last constant PMBUS_HAVE_IIN was not OR-ed with the other
PM_BUS_HAVE_* constants for this page but it initialized the next element
of the func array (which was not accessed from anywhere because of the
number of pages).
However, there is no need for setting PMBUS_HAVE_IIN in the 5Vsb page
because this command does not seem to be paged. Obviously, the device
only has one IIN sensor, so it doesn't make sense to query it again from
the second page.

Extend aquacomputer_d5next driver to expose various hardware sensors of the
Aquacomputer Aquastream XT watercooling pump, which communicates
through a proprietary USB HID protocol. Implemented by Leonard Anderweit
[1] [2].
Coolant temp, fan IC and external temp sensor readings are available, along
with speed and voltage of both the pump and optionally connected fan.
It also exposes pump current.
Additionally, serial number and firmware version are exposed through
debugfs.

TPM specification [1] defines flow control over SPI. Client device can
insert a wait state on MISO when address is transmitted by controller
on MOSI. Detecting the wait state in software is only possible for
full duplex controllers. For controllers that support only half-
duplex, the wait state detection needs to be implemented in hardware.
Add a flag SPI_TPM_HW_FLOW for TPM device to set when software flow
control is not possible and hardware flow control is expected from
SPI controller.

For some unknown reason the introduction of the timer_wait_running callback
missed to fixup posix CPU timers, which went unnoticed for almost four years.
Marco reported recently that the WARN_ON() in timer_wait_running()
triggers with a posix CPU timer test case.
Posix CPU timers have two execution models for expiring timers depending on
CONFIG_POSIX_CPU_TIMERS_TASK_WORK:
1) If not enabled, the expiry happens in hard interrupt context so
spin waiting on the remote CPU is reasonably time bound.
Implement an empty stub function for that case.
2) If enabled, the expiry happens in task work before returning to user
space or guest mode. The expired timers are marked as firing and moved
from the timer queue to a local list head with sighand lock held. Once
the timers are moved, sighand lock is dropped and the expiry happens in
fully preemptible context. That means the expiring task can be scheduled
out, migrated, interrupted etc. So spin waiting on it is more than
suboptimal.
The timer wheel has a timer_wait_running() mechanism for RT, which uses
a per CPU timer-base expiry lock which is held by the expiry code and the
task waiting for the timer function to complete blocks on that lock.
This does not work in the same way for posix CPU timers as there is no
timer base and expiry for process wide timers can run on any task
belonging to that process, but the concept of waiting on an expiry lock
can be used too in a slightly different way:
- Add a mutex to struct posix_cputimers_work. This struct is per task
and used to schedule the expiry task work from the timer interrupt.
- Add a task_struct pointer to struct cpu_timer which is used to store
a the task which runs the expiry. That's filled in when the task
moves the expired timers to the local expiry list. That's not
affecting the size of the k_itimer union as there are bigger union
members already
- Let the task take the expiry mutex around the expiry function
- Let the waiter acquire a task reference with rcu_read_lock() held and
block on the expiry mutex
This avoids spin-waiting on a task which might not even be on a CPU and
works nicely for RT too.

Get rid of conditional compilation based on CONFIG_PM_SLEEP because
it may introduce build issues with certain configs where it maybe disabled
This is because if above config is not enabled the suspend-resume
functions are never part of the code but the bcm63xx_spi_pm_ops struct
still inits them to non-existent suspend-resume functions.
