scsi: scsi_debug: Add support to corrupt data and/or reftag
Add a new debugfs file to inject corruptions of the data and/or reftag.
This will be used to detect that protection information and/or file
system checksumming can detect random bit errors or misplaced writes.
To use this echo the start LBA, number of logical blocks and type of
corruption into the new "corrupt" debugfs file for each scsi_debug
device.
For example:
echo lba=42,num=1,bit_errors=2 > /sys/kernel/debug/scsi_debug/1:0:0:0/corrupt
or
echo lba=2,num=4,reftag_adjust=8 > /sys/kernel/debug/scsi_debug/1:0:0:0/corrupt
The injection will be used by new xfstests test cases.
