scsi_debug dsense lk2.6.11-rc1
PATCH 1/1 scsi_debug dsense lk2.6.11-rc1
The dsense switch in the scsi_debug driver selects whether fixed (default) or descriptor format sense data is returned when an error/warning occurs. Due to an oversight dsense was not sysfs visible.
James, will the new generic device transport class be useful for the scsi_debug driver. At the moment it uses a "pseudo" device and bus type. When I tried to replicate that structure in another virtual driver (for a SES target) I found that the two drivers didn't play well together.
Changelog:
- make dsense visible to sysfs
