I don't know about the original flush_to_ldisc, but
I designed the above code to protect against parallel calls
knowing I could not hold a spinlock when calling receive_buf.

TTY_FLUSHING came later. The problem associated
with that addition proves my code is obscure enough to make
maintenance difficult. I got confused reviewing my own code
yesterday.

Boo hoo, live and learn.
