We need to flush the btree key cache when it's too dirty, because otherwise the shrinker won't be able to reclaim memory - this is done by journal reclaim. But journal reclaim also kicks btree node writes: this meant that btree node writes were getting kicked much too often just because we needed to flush btree key cache keys. This patch splits journal pins into two different lists, and teaches journal reclaim to not flush btree node writes when it only needs to flush key cache keys.

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.
