Linux kernel source tree
93c60b17f2
The preemptive flushing code was added in order to avoid needing to
synchronously wait for ENOSPC flushing to recover space. Once we're
almost full however we can essentially flush constantly. We were using
98% as a threshold to determine if we were simply full, however in
practice this is a really high bar to hit. For example reports of
systems running into this problem had around 94% usage and thus
continued to flush. Fix this by lowering the threshold to 90%, which is
a more sane value, especially for smaller file systems.

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.
