Other parts of XFS have learned to call xfs_blockgc_free_{space,quota}
to try to free speculative preallocations when space is tight. This
means that file writes, transaction reservation failures, quota limit
enforcement, and the EOFBLOCKS ioctl all call this function to free
space when things are tight.
Since inode inactivation is now a background task, this means that the
filesystem can be hanging on to unlinked but not yet freed space. Add
this to the list of things that xfs_blockgc_free_* makes writer threads
scan for when they cannot reserve space.

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.
