Static analysis reports this problem
free-space-cache.c:3965:2: warning: Undefined or garbage value returned
return ret;
^~~~~~~~~~
ret is set in the node handling loop. Treat doing nothing as a success
and initialize ret to 0, although it's unlikely the loop would be
skipped. We always have block groups, but as it could lead to
transaction abort in the caller it's better to be safe.

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.
