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.
