nilfs_sufile_do_free(), which is called when log write fails or during GC, uses WARN_ONs to check for abnormal status of metadata. In the former case, these WARN_ONs will not be fired, but in the latter case they don't "never-happen". It is possible to trigger these by intentionally modifying the userland GC library to release segments that are not in the expected state. So, replace them with warning output using the dedicated macro nilfs_warn(). This replaces two potentially triggered WARN_ONs with ones that use a warning output macro.

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.
