A common characteristic of the bug report where preemptive flushing was going full tilt was the fact that the vast majority of the free metadata space was used up by the global reserve. The hard 90% threshold would cover the majority of these cases, but to be even smarter we should take into account how much of the outstanding reservations are covered by the global block reserve. If the global block reserve accounts for the vast majority of outstanding reservations, skip preemptive flushing, as it will likely just cause churn and pain.

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.
