I think you're missing the point. The only mechanism with which
scsipi_run_queue can be called now after a thaw is via the indirect softcall
mechanism in scsipi_channel_thaw (which is exposed). I don't care whether
scsipi_run_queue itself is private. I *do* care that you can't restart except
via a softcall. That's just plain wrong when you've already got a per-HBA
thread.
