sys/kern : tty.c tty_pty.c
Log message:
Adjust pty and tty event filters
* Implement EVFILT_EXCEPT for ttys for HUP condition detection.
This filter is used when pollfd.events has no read/write events.
* Add HUP condition detection to filt_ptcwrite() and filt_ttywrite()
to reflect ptcpoll() and ttpoll(). Only poll(2) and select(2) can
utilize the code; kevent(2) should behave as before with EVFILT_WRITE.
* Clear EV_EOF and __EV_HUP if the EOF/HUP condition ends.
OK mpi@
