This is prep work for snapshots: the algorithm in bch2_extent_sort_fix_overlapping() will break when we have multiple overlapping extents in unrelated snapshots - but, we'll be able to make extents work like regular keys and use bch2_key_sort_fix_overlapping() for extent btree nodes if we make a couple changes - the main one being to always emit new extents when we partially overwrite an existing (written) extent.

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.
