Previously, we were doing btree node merging from bch2_btree_insert_node() - but this is called from the split path, when we're in the middle of creating new nodes and deleting new nodes and the iterators are in a weird state. Also, this means we're starting a new btree_update while in the middle of an existing one, and that's asking for deadlocks. Much simpler and saner to trigger btree node merging _after_ the whole btree node split path is finished.

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.
