At btrfs_split_ordered_extent(), we are removing and re-inserting the ordered extent that we are trimming, but we don't need to since the trimming doesn't change its position in the red black tree because we don't have overlapping ordered extents (that would imply double allocation of extents) and we know the split length is smaller than the ordered extent's num_bytes field (we checked that early in the function). So drop the remove and re-insert code for the slit ordered 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 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.
