ed 2009-12-01 19:14:57 UTC FreeBSD src repository Modified files: sys/kern tty.c Log: SVN rev 199998 on 2009-12-01 19:14:57Z by ed Don't allocate an input buffer for a TTY when the receiver is turned off. When the termios CREAD flag is not set, it makes little sense to allocate an input buffer. Just set the size to 0 in this case to reduce memory footprint. Disallow CREAD to be disabled for pseudo-devices to prevent foot-shooting. Revision Changes Path 1.334 +4 -2 src/sys/kern/tty.c
