Hi Greg, This patchset replaces the printk(KERN_DEBUG) uses in the tty core with a common tty_debug(tty, ...) base macro, folding in the common elements of tty name and function name. The many inline #ifdef TTY_SOME_DEBUG_FLAG printk's are replaced with macro equivalents which reduce to tty_debug(). Several important improvements include: * patch 1/7 adds the tty count to the tty_open() message * patch 6/7 improve the ldisc messages to aid in state debugging * patch 7/7 adds pmtx open (which helps clarify when the master was opened) An important outcome of a single tty_debug() macro is that it can be trivially changed to use a different debug facility than console; for example, for some of my torture tests using the ftrace facility is much less intrusive. I would expect that to remain a local change though.
