David Sterba 9594783e4b btrfs: print-tree: use string format for key names
There's a warning when -Wformat=2 is used:

fs/btrfs/print-tree.c: In function ‘key_type_string’:
fs/btrfs/print-tree.c:424:17: warning: format not a string literal and no format arguments [-Wformat-nonliteral]
  424 |                 scnprintf(buf, buf_size, key_to_str[key->type]);

We're printing fixed strings from a table so there's no problem but
let's fix the warning so we could enable the warning in fs/btrfs/.

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.
