When doing some testing recently, I hit some page allocation failures on mount, when creating the wb_pagevec_pool for the mount. That requires 128k (32 contiguous pages), and after thrashing the memory during an xfstests run, sometimes that would fail. 128k for each mount seems like a lot to hold in reserve for a rainy day, so let's change this to a global mempool that gets allocated when the module is plugged in.

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.
