David Sterba 5ab2b18088 btrfs: factor out validation of btrfs_ioctl_vol_args::name
The validation of vol args name in several ioctls is not done properly.
a terminating NUL is written to the end of the buffer unconditionally,
assuming that this would be the last place in case the buffer is used
completely. This does not communicate back the actual error (either an
invalid or too long path).

Factor out all such cases and use a helper to do the verification,
simply look for NUL in the buffer. There's no expected practical change,
the size of buffer is 4088, this is enough for most paths or names.

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.
