Subject: [RFC PATCH 0/5] scsi:scsi_debug:Add error injection for single lun

The original error injection mechanism was based on scsi_host which
could not inject fault for a single SCSI device.

This patchset provides the ability to inject errors for a single
SCSI device. Now we supports inject timeout errors, queuecommand
errors, and hostbyte, driverbyte, statusbyte, and sense data for
specific SCSI Command

The first patch add an sysfs interface to add and inquiry single
device's error injection info; the second patch defined how to remove
an injection which has been added. The following 3 patches use the
injection info and generate the related error type.

Wenchao Hao (5):
  scsi:scsi_debug: Add sysfs interface to manager single devices' error inject
  scsi:scsi_debug: Add interface to remove injection which has been added
  scsi:scsi_debug: make command timeout if timeout error is injected
  scsi:scsi_debug: Return failed value for specific command's queuecommand
  scsi:scsi_debug: fail specific scsi command with result and sense data
