Daniel Rosenberg e81cea2a6f ANDROID: vfs: Add permission2 for filesystems with per mount permissions 
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.

[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.

README 

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
