[1] I propose a small change to scsi_tgt_lib.c that will make tgt completely neutral to the scsi_data_buffer patch. And will make it all that more ready for bidi, too. TOMO is this OK? (Can you do without the GFP_KERNEL allocation flag? It could make the code a bit more simple)
GFP_KERNEL is nice for the target layer because it can sleep in that path you changed and it and does not have the "cannot write out pages because it may come back to the same device issues" like an initiator does.
If we ever changed to a softirq instead of the work queue then we would not need the flag since it would have to GFP_ATOMIC, but I am not sure if we have plans to do that anytime soon.
