dm-user is essentially FUSE for block devices: as BIOs come in through
device mapper they are proxied to a userspace daemon via a control misc
device.
This is very much a work in progress. There's a handful of FIXMEs
spread throughout the code with more details. As far as I know there is
nothing broken with the current code, there's just more work to do.
Test: Ran the selftests on the version of this I'm developing for Linus'
tree, on both 4.19 and 5.8.

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.
