Yeah, makes sense. And any SG_IO test should be able to run on both block device nodes and sg nodes.

Maybe I can even clean it up a bit so it compiles with the "-Wall -Wextra -Werror" trinity. I'll send you a v2 once I'm done with it (and all other comments).

The test included is doesn't hit the SG_IO path in the sg driver, but the sg_read path. Of cause we can make a generic sg_io tool but IMHO it's quite convenient to just throw in the reproducers we get. And as it exercises the /dev/sg character device I decided to make a new group.

Re: [PATCH blktests 0/3] Add SCSI generic test group
All SG_IO test should also apply to block device nodes that support the ioctl..
