Josef Bacik e6549c2aab btrfs: allow to use up to 90% of the global block rsv for unlink
We previously had a limit of stealing 50% of the global reserve for
unlink.  This was from a time when the global reserve was used for the
delayed refs as well.  However now those reservations are kept separate,
so the global reserve can be depleted much more to allow us to make
progress for space restoring operations like unlink.  Change the minimum
amount of space required to be left in the global reserve to 10%.

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.
