The v4l2_fh initialized and added in vpu_v4l2_open() is delete and
cleaned up when the last reference to the vpu_inst is released. This may
happen later than at vpu_v4l2_close() time.
Not deleting and cleaning up the v4l2_fh when closing the file handle to
the video device is not ideal, as the v4l2_fh will still be present in
the video device's fh_list, and will store a copy of events queued to
the video device. There may also be other side effects of keeping alive
an object that represents an open file handle after the file handle is
closed.
The v4l2_fh instance is embedded in the vpu_inst structure, and is
accessed in two different ways:
- in vpu_notify_eos() and vpu_notify_source_change(), to queue V4L2
events to the file handle ; and
- through the driver to access the v4l2_fh.m2m_ctx pointer.
The v4l2_fh.m2m_ctx pointer is not touched by v4l2_fh_del() and
v4l2_fh_exit(). It is set to NULL by the driver when closing the file
handle, in vpu_v4l2_close().
The vpu_notify_eos() and vpu_notify_source_change() functions are called
in vpu_set_last_buffer_dequeued() and vdec_handle_resolution_change()
respectively, only if the v4l2_fh.m2m_ctx pointer is not NULL. There is
therefore a guarantee that no new event will be queued to the v4l2_fh
after vpu_v4l2_close() destroys the m2m_ctx.
The vpu_notify_eos() function is also called from vpu_vb2_buf_finish(),
which is guaranteed to be called for all queued buffers when
vpu_v4l2_close() calls v4l2_m2m_ctx_release(), and will not be called
later.
It is therefore safe to assume that the driver will not touch the
v4l2_fh, except to check the m2m_ctx pointer, after vpu_v4l2_close()
destroys the m2m_ctx. We can safely delete and cleanup the v4l2_fh
synchronously in vpu_v4l2_close().

The ivtv driver has a structure named ivtv_open_id that models an open
file handle for the device. It embeds a v4l2_fh instance for file
handles that correspond to a V4L2 video device, and stores a pointer to
that v4l2_fh in struct ivtv_stream to identify which open file handle
owns a particular stream.
In addition to video devices, streams can be owned by ALSA PCM devices.
Those devices do not make use of the v4l2_fh instance for obvious
reasons, but the snd_ivtv_pcm_capture_open() function still initializes
a "fake" v4l2_fh for the sole purpose of using it as an open file handle
identifier. The v4l2_fh is not properly destroyed when the ALSA PCM
device is closed, leading to possible resource leaks.
Fortunately, the v4l2_fh instance pointed to by ivtv_stream is not
accessed, only the pointer value is used for comparison. Replace it with
a pointer to the ivtv_open_id structure that embeds the v4l2_fh, and
don't initialize the v4l2_fh for ALSA PCM devices.

Together with the RAPL MSRs, there are more MSRs gone on DMR, including
PLR (Perf Limit Reasons), and IRTL (Package cstate Interrupt Response
Time Limit) MSRs. The configurable TDP info should also be retrieved
from TPMI based Intel Speed Select Technology feature.
Remove the access of these MSRs for DMR. Improve the DMR platform
feature table to make it more readable at the same time.

We have out-grown the ability to use a 64-bit memory location
to inventory every possible built-in counter.
Leverage the the CPU_SET(3) macros to break this barrier.
Also, break the Joules & Watts counters into two,

Here is a single revert of one of the previous patches that went in the
last tty/serial merge that is breaking userspace on some platforms
(specifically powerpc, probably a few others.) It accidentially changed
the ioctl values of some tty ioctls, which breaks xorg.
The revert has been in linux-next all this week with no reported issues.

Merge tag 'io_uring-6.17-20250808' of git://git.kernel.dk/linux
Pull io_uring fixes from Jens Axboe:
- Allow vectorized payloads for send/send-zc - like sendmsg, but
without the hassle of a msghdr.
- Fix for an integer wrap that should go to stable, spotted by syzbot.
Nothing alarming here, as you need to be root to hit this.
Nevertheless, it should get fixed.
FWIW, kudos to the syzbot crew for having much nicer reproducers now,
and with nicely annotated source code as well. This is particularly
useful as syzbot uses the raw interface rather than liburing,
historically it's been difficult to turn a syzbot reproducer into a
meaningful test case. With the recent changes, not true anymore!
