Historically we only set the capacity to zero for devices that support
partitions (independ of actually having partitions created). Doing that
is rather inconsistent, but changing it broke legacy udisks polling for
legacy ide-cdrom devices. Use the crude a crude check for devices that
either are non-removable or partitionable to get the sane behavior for
most device while not breaking userspace for this particular setup.

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.
