Some errors may need to be fixed in order for GC to successfully run - walk and mark all metadata. But we can't start the allocators and do normal btree updates until after GC has completed, and allocation information is known to be consistent, so we need a different method of doing btree updates. Fortunately, we already have code for walking the btree while overlaying keys from the journal to be replayed. This patch adds an update path that adds keys to the list of keys to be replayed by journal replay, and also fixes up iterators.

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.
