Greg, This patchset contains no bug fixes only misc cleanup for the N_TTY line discipline. Patches 1-4 cleans up code duplication remnants from 3.12's changes. Patch 5 simplifies the snarled logic of how much data is considered 'input available'. I was getting tired of hand checking that logic every time I touched minimum_to_wake. Patch 6 reduces unnecessary wake ups. Patch 7 extends the trace usage to aid in identifying and fixing input flow-control bugs (this was used to fix the readline() bug). I also expect to use it to reduce input processing restarts. It's use is disabled by default and only enabled with the file-local define N_TTY_TRACE (similar to TTY_DEBUG_HANGUP in tty_io.c).
