Ben Shelton 7bccd12d27 ubi: Add debugfs file for tracking PEB state
Add a file under debugfs to allow easy access to the erase count for
each physical erase block on an UBI device.  This is useful when
debugging data integrity issues with UBIFS on NAND flash devices.

v2:
* If ubi_io_is_bad eraseblk_count_seq_show just returns the err.
* if ubi->lookuptbl returns null, its no longer treated as an error
  instead info for that block is not printeded
* Removed check for UBI_MAX_ERASECOUNTER since it is impossible to hit
* Removed block state from print, if a block is printed then it is good and
  if it is not printed, then it is bad.

v3:
* Remove errant ! symbol from if statement checking if erase count is valid.

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.
