commit f63e1164b90b385cd832ff0fdfcfa76c3cc15436 upstream. An ordered extent completing is a critical moment in qgroup reserve handling, as the ownership of the reservation is handed off from the ordered extent to the delayed ref. In the happy path we release (unlock) but do not free (decrement counter) the reservation, and the delayed ref drives the free. However, on an error, we don't create a delayed ref, since there is no ref to add. Therefore, free on the error path.

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.
