Previously the seq_buf used for accumulating the memory.stat output was sized at PAGE_SIZE. But the amount of output is invariant to PAGE_SIZE; If 4K is enough on a 4K page system, then it should also be enough on a 64K page system, so we can save 60K on the static buffer used in mem_cgroup_print_oom_meminfo(). Let's make it so. This also has the beneficial side effect of removing a place in the code that assumed PAGE_SIZE is a compile-time constant. So this helps our quest towards supporting boot-time page size selection.

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 reStructuredText 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.
