This allows filesystems to use their mount private data to
influence the permssions they return in permission2. It has
been separated into a new call to avoid disrupting current
permission users.
Test: HiKey/X15 + Pie + android-mainline,
and HiKey + AOSP Maser + android-mainline,
directories under /sdcard created,
output of mount is right,
CTS test collecting device infor works

[AmitP: Minor refactoring of original patch to align with
changes from the following upstream commit
4bfd054ae1 ("fs: fold __inode_permission() into inode_permission()").
Also introduce vfs_mkobj2(), because do_create()
moved from using vfs_create() to vfs_mkobj()
eecec19d9e ("mqueue: switch to vfs_mkobj(), quit abusing ->d_fsdata")
do_create() is dropped/cleaned-up upstream so a
minor refactoring there as well.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
