commitb54e41f5efupstream. Commitc26f6c6157("udf: Fix conversion of 'dstring' fields to UTF8") started to be more strict when checking whether converted strings are properly formatted. Sudip reports that there are DVDs where the volume identification string is actually too long - UDF reports: [ 632.309320] UDF-fs: incorrect dstring lengths (32/32) during mount and fails the mount. This is mostly harmless failure as we don't need volume identification (and even less volume set identification) for anything. So just truncate the volume identification string if it is too long and replace it with 'Invalid' if we just cannot convert it for other reasons. This keeps slightly incorrect media still mountable.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
