At btrfs_set_inode_index_count() we refer twice to the number 2 as the initial index value for a directory (when it's empty), with a proper comment explaining the reason for that value. In the next patch I'll have to use that magic value in the directory logging code, so put the value in a #define at btrfs_inode.h, to avoid hardcoding the magic value again at tree-log.c.

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.
