Changes for v2: rebased on top of tty-next Hi Greg, This series removes ASYNC_CLOSING from kernel use. However, the definition is in a uapi header so I think it needs to stay. The mxser driver used ASYNC_CLOSING to purge its fifo _with each byte received_ while closing. This is clearly unnecessary but the hangup/shutdown sequence in that driver is spaghetti and I don't have the hardware to test (what I would consider to be) the proper fix: cleaning up its hangup/shutdown so that clearing the fifo can be done once in shutdown. The isdn subsystem used ASYNC_CLOSING for unclear purposes; the immediate effect was to prevent sending AT commands from the emulator, but its not clear why that's necessary when closing. Since idsn does not use the tty_port helpers, I simply added to isdn the equivalent of an ASYNC_CLOSING flag.
