Actually, volume name doesn't need to include the NIL terminator if
the string length matches the on-disk field size as mentioned in [1].
I tend to relax it together with the upcoming 48-bit block addressing
(or stable kernels which backport this fix) so that we could have a
chance to record a 16-byte volume name like ext4.
Since in-memory `volume_name` has no user, just get rid of the unneeded
check for now. `sbi->uuid` is useless and avoid it too.

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 reStructuredText 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.
