Miaohe Lin 71f9e58eb4 mm/huge_memory.c: rework the function vma_adjust_trans_huge()
Patch series "Some cleanups for huge_memory", v3.

This series contains cleanups to rework some function logics to make it
more readable, use helper function and so on.  More details can be found
in the respective changelogs.

This patch (of 6):

The current implementation of vma_adjust_trans_huge() contains some
duplicated codes.  Add helper function to get rid of these codes to make
it more succinct.

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.
