Liam Howlett 92b7399695 mmap: fix copy_vma() failure path 
The anon vma was not unlinked and the file was not closed in the failure
path when the machine runs out of memory during the maple tree
modification.  This caused a memory leak of the anon vma chain and vma
since neither would be freed.

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.

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.
