Conny what do you think?What do you mean with "old releases"? The dstream rework was in 2.11, and I doubt that anyone is using anything older, or a downstream release that is based on pre-2.11. If you mean "include in stable", then yes, we can do that; if we want the commit in 6.0, I need the final version soon.
OK, are you OK with the two change propositions I sent?1) let the 3270 decide for internal errors (-EIO) but return the error for CSS errors in handle_payload_3270_write()
2) for senseid, always ask CSS to update the residual count but only erase the senseid if the write succeeded -- Pierre Morel IBM Lab Boeblingen
