Liam R. Howlett 94d815b279 mm/khugepaged: optimize collapse_pte_mapped_thp() by using vma_lookup()
vma_lookup() will walk the vma tree once and not continue to look for the
next vma.  Since the exact vma is checked below, this is a more optimal
way of searching.

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.
