When we're adding extents to the busy discard list, add them to the tail
of the list so that we get FIFO order. For FITRIM commands, this means
that we send discard bios sorted in order from longest to shortest, like
we did before commit 89cfa899608fc.
For transactions that are freeing extents, this puts them in the
transaction's busy list in FIFO order as well, which shouldn't make any
noticeable difference.
Fixes: 89cfa899608fc ("xfs: reduce AGF hold times during fstrim operations")

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.
