This patch adds support for an optional MTD label for mtd2block emulated
MTD devices. Useful when, e.g., testing device images using Qemu.
The following line in /etc/fstab can then be used to mount a file system
regardless if running on an embedded system, or emulated with block2mtd:
mtd:Config /mnt jffs2 noatime,nodiratime 0 0
Kernel command line syntax in the emulated case:
block2mtd.block2mtd=/dev/sda,,Config
Notice the ',,' it is the optional erase_size, which like before this
patch, defaults to PAGE_SIZE when omitted. Hence the strlen() check.

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.
