Add some helpers to assemble a list of fs block extents. Generally, repair functions will iterate the rmapbt to make a list (1) of all extents owned by the nominal owner of the metadata structure; then they will iterate all other structures with the same rmap owner to make a list (2) of active blocks; and finally we have a subtraction function to subtract all the blocks in (2) from (1), with the result that (1) is now a list of blocks that were owned by the old btree and must be disposed.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
