This reverts commit 7eec77a181.
Instead of leaving disk->events completely empty, we now export the
supported events again, and tell the block layer not to forward events
to user space by not setting DISK_EVENT_FLAG_UEVENT. This allows the
block layer to distinguish between devices that for which events should
be handled in kernel only, and devices which don't support any meda
change events at all.

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.
