This patch is based on 1699785. It uses to extend the related interface
to support the request-based operations. We use extension fields in the
parameters of VIDIOC_SUBDEV_S_SELECTION, VIDIOC_SUBDEV_S_FMT and
VIDIOC_SUBDEV_S_FRAME_INTERVAL as request fd.
The driver uses media_request_get_by_fd() to retrieve the media request and
save the pending change in it, so that we can apply the pending change in
req_queue() callback then.

"dev_name" for I2C devices won't have any value set, unless they are
instantiated thru ACPI interface. As a result of this, I2C driver will
assign some dynamic name in the format "%d-%04x" (e.g. 1-001f), and
further this device names are used for kernel wakelocks.
This dynamic names are difficult to associate with actual device and
hence it will help to have an ability where vendor can assign the
device name through vendor hooks.

in below issue.
(https://issuetracker.google.com/issues/162776704)
There are vendor hook call in mutex and rw_semaphore, but not for rt_mutex
Please refer to description in details as below,
1. Description
This feature writes rt mutex lock waiting information
on the task_struct structure. We can check mutex information and
mutex owner through the kernel log and custom analysis tools.
Like the previous feature in mutex and rw semaphore,
added data can be checked by ramdump analysis.
2. Vendor Hook Position
1) VENDOR_DATA
- struct task_struct in sched.h
VENDOR_DATA_ARRAY(2)
[0] : type // RTmutex (Mutex, Rwsem, ...)
[1] : pointer // address of lock
2) VENDOR_HOOKs
- __rt_mutex_slowlock() in kernel/locking/rtmutex.c
3. Example
- SysRq-w in kernel log

In Android GKI, CONFIG_FAIR_GROUP_SCHED is enabled [1] to help
prioritize important work. Given that CPU shares of root cgroup
can't be changed, leaving the tasks inside root cgroup will give
them higher share compared to the other tasks inside important
cgroups. This is mitigated by moving all tasks inside root cgroup to
a different cgroup after Android is booted. However, there are many
kernel tasks stuck in the root cgroup after the boot.
It is possible to relax kernel threads and kworkers migrations under
certain scenarios. However the patch [2] posted at upstream is not
accepted. Hence add a restricted vendor hook to notify modules when a
kernel thread is requested for cgroup migration. The modules can relax
the restrictions forced by the kernel and allow the cgroup migration.
