Buffered writers who have run out of quota reservation call xfs_inode_free_quota_blocks to try to free any space reservations that might reduce the quota usage. Unfortunately, the buffered write path treats "out of project quota" the same as "out of overall space" so this function has never supported scanning for space that might ease an "out of project quota" condition. We're about to start using this function for cases where we actually /can/ tell if we're out of project quota, so add in this functionality. Signed-off-by: Darrick J.

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.
