Re: [BK PATCH] SCSI updates for 2.6.9

[Linus Torvalds]

Ben,
 does this look ok to you?

Arguably the SCSI layer should also have proper prefixes for its constants
- and in fact they do kind of exist as the GPCMD_xxx constants.  Oh, well.
Regardless, the sbp2 constants do look like they want prefixing..
