Al Viro 0fbe2a72e8 memcg_write_event_control(): fix a user-triggerable oops
commit 046667c4d3196938e992fba0dfcde570aa85cd0e upstream.

we are *not* guaranteed that anything past the terminating NUL
is mapped (let alone initialized with anything sane).

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.
