blk_mark_disk_dead does very similar work a a section of del_gendisk: - set the GD_DEAD flag - set the capacity to zero - start a queue drain but del_gendisk also sets QUEUE_FLAG_DYING on the queue if it is owned by the disk, sets the capacity to zero before starting the drain, and both with sending a uevent and kernel message for this fake capacity change. Move the exact logic from the more heavily used del_gendisk into blk_mark_disk_dead and then call blk_mark_disk_dead from del_gendisk.

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.
