When debugging the recent ram_bytes mismatch bug, I can hit it with enhanced tree-checker for file extent items at write time. But the bug is not that easy to trigger (mostly triggered with btrfs/06*, which uses 20 threads fsstress), and when I hit it, the only info is the kernel leaf dump, but it doesn't include things like the file extent type (REGULAR or PREALLOC). Add the dump for generation and type (although only numeric output) to make debugging a little easier.

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.
