Rabin Vincent 319c104274 ubifs: allow userspace to map mounts to volumes
There currently appears to be no way for userspace to find out the
underlying volume number for a mounted ubifs file system, since ubifs
uses anonymous block devices.  The volume name is present in
/proc/mounts but UBI volumes can be renamed after the volume has been
mounted.

To remedy this, show the UBI number and UBI volume number as part of the
options visible under /proc/mounts.

Also, accept and ignore the ubi= vol= options if they are used mounting
(patch from Richard Weinberger).

 # mount -t ubifs ubi:baz x
 # mount
 ubi:baz on /root/x type ubifs (rw,relatime,ubi=0,vol=2)
 # ubirename /dev/ubi0 baz bazz
 # mount
 ubi:baz on /root/x type ubifs (rw,relatime,ubi=0,vol=2)
 # ubinfo -d 0 -n 2
 Volume ID:   2 (on ubi0)
 Type:        dynamic
 Alignment:   1
 Size:        67 LEBs (1063424 bytes, 1.0 MiB)
 State:       OK
 Name:        bazz
 Character device major/minor: 254:3

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.
