When performing memory reclaim, support treating anonymous and
file backed pages equally. Swapping anonymous pages out to memory
can be efficient enough to justify treating anonymous and file backed
pages equally.
Create a vendor hook inside of get_scan_count so that equal reclaim of
anon and file pages can be enabled inside of the trace hook based on
certain conditions.

This patch is to extend the related interface to support the request-based operations. We use extension fields in the parameters of MEDIA_IOC_SETUP_LINK, VIDIOC_S_FMT, VIDIOC_SUBDEV_S_SELECTION, VIDIOC_SUBDEV_S_FMT 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.
Besides, We also add three vendor hook functions to handle related changes in v4l2-framework.

[ Upstream commit 6cf23783f7 ]
This tracepoint can crash when dereferencing snd_task because
when some transports connect, they put a cookie in that field
instead of a pointer to an rpc_task.

Like other filesystem does, we introduce a new file f2fs.h in path of
include/uapi/linux/, and move f2fs-specified ioctl interface definitions
to that file, after then, in order to use those definitions, userspace
developer only need to include the new header file rather than
copy & paste definitions from fs/f2fs/f2fs.h.

"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.

We already applied the 'vendor hook' for Dtask Debugging Information
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.

There were missing places to add cma instance name. To identify each CMA
instance, let's add the name for every cma trace. This patch also changes
the existing cma_trace_alloc to cma_trace_finish since we have
cma_alloc_start[1].
