Laurence Oberman d9da891a89 scsi: scsi_debug: Add two new parameters to scsi_debug driver
This patch adds two new parameters to the scsi_debug driver.

During various fault injection scenarios it would be useful to be able
to pick a specific starting sector and number of follow on sectors where
a MEDIUM ERROR for reads would be returned against a scsi-debug device.

Right now this only works against sector 0x1234 and OPT_MEDIUM_ERR_NUM
follow on sectors.  However during testing of md-raid and other
scenarios I wanted more flexibility.

The idea is add 2 new parameters:

    medium_error_start
    medium_error_count

If medium_error_start is set then we don't use the default of
OPT_MEDIUM_ERR_ADDR, but use that set value.

If medium_error_count is set we use that value otherwise default to
OPT_MEDIUM_ERR_NUM.

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.
