Josef Bacik d792b0f197 btrfs: always reserve our entire size for the global reserve
While messing with the overcommit logic I noticed that sometimes we'd
ENOSPC out when really we should have run out of space much earlier.  It
turns out it's because we'll only reserve up to the free amount left in
the space info for the global reserve, but that doesn't make sense with
overcommit because we could be well above our actual size.  This results
in the global reserve not carving out it's entire reservation, and thus
not putting enough pressure on the rest of the infrastructure to do the
right thing and ENOSPC out at a convenient time.  Fix this by always
taking our full reservation amount for the global reserve.

README

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.
