The code that checked the current free space and waited if it was too big was causing issues - btree node allocations do not increment the write IO clock (perhaps they should); but more broadly the check wouldn't run copygc at all until the device was mostly full, at which point it might have to do a bunch of work. This redoes that logic so that copygc starts to run earlier, smoothly running more and more often as the device becomes closer to full.

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.
