It would be nice if the SCSI core supported the concept of "channel
busy". SCSI understands host-busy and device-busy.
Right now libata allocates one scsi host per ATA port largely due to
SCSI implementation details, and I would like to get away from that.

True - and we've been dancing around target busy as well. Basically,
if there's an HCIL, any component of the HCIL could potentially be busy.
And, stirring the pot, there could be different queuing/resource limits
at each point as well.
