Shawn Lin 57678e5a3d mmc: block: Delete gendisk before cleaning up the request queue dd if=/dev/urandom of=/dev/mmcblk1 bs=4k count=10000 with a SD card hotplug during transfer reports a warning below introduced by commit `a063057d7c` ("block: Fix a race between request queue removal and the block cgroup controller"). So we should now remove the disk, partition and bdi sysfs attributes before cleaning up the request queue associated with the disk.

README

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

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.
