Since 'snprintf()' returns the number of characters which would
be emitted and output truncation is handled by 'ASSERT()', it
should be safe to use that return value instead of the subsequent
calls to 'strlen()' in 'gen_unique_name()'.
This also reduces the module's text size.
Before:
$ size fs/btrfs/btrfs.ko
text data bss dec hex filename

After:
$ size fs/btrfs/btrfs.ko
text data bss dec hex filename

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.
