[PATCH] scsi_debug dsense lk2.6.11-rc1

[PATCH] scsi_debug dsense lk2.6.11-rc1

[Douglas Gilbert]

[-- Attachment #1: Type: text/plain, Size: 583 bytes --]

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
