Add some debug knobs so that we can control the leaf and node block slack when rebuilding btrees. For developers, it might be useful to construct btrees of various heights by crafting a filesystem with a certain number of records and then using repair+knobs to rebuild the index with a certain shape. Practically speaking, you'd only ever do that for extreme stress testing of the runtime code or the btree generator. Signed-off-by: Darrick J.

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.
