CVS commit: [vmlocking] src/sys

[Andrew Doran <ad%netbsd.org@localhost>]

Module Name:    src
Committed By:   ad
Date:           Fri Oct 19 15:54:29 UTC 2007

Modified Files:
        src/sys/kern [vmlocking]: init_main.c tty.c tty_conf.c tty_pty.c
        src/sys/sys [vmlocking]: tty.h

Log Message:
In the tty code, defer posting singals to a soft interrupt. Avoids
touching process state from a hardware interrupt, and avoids locking
problems (tty_lock is always held when the signals are sent).
