Jiri Olsa 53da12e013 perf ordered_events: Prevent crossing max_alloc_size
Stephane reported a possible issue in the ordered events code, which
could lead to allocating more memory than guarded by max_alloc_size.

He also suggested the fix to properly check that the new size is below
the max_alloc_size limit.

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.
