This code needs quite a bit of work: we don't want to be walking all metadata in the filesystem, we should just be walking backpointers, and it should be switched to a data ioctl that can report progress via a file descriptor, not the system console. But that'll take more work - before we can safely walk only backpointers we need to change device add to not reuse device indexes, since with that change accounting being wrong introduces the possibility of removing a device that still has pointers.

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.
