Bisection shows that this brokenness is introduced by git-scsi-misc.patch.

Someone has gone in and made some ill-advised "improvements" to
/proc/scsi/scsi.  The switch from "Direct-Access" to "Direct access" broke
ofpath.  I fixed that (in ofpath) but it remains broken for other reasons.

James, this is a non-compatible change to the kernel->userspace interface.  Please
drop it like a hot potato.
