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.
