sys/kern tty.c
Log:
SVN rev 184167 on 2008-10-22 15:43:28Z by jhb
MFC: Close a race in the kern.ttys sysctl handler that resulted in panics
in dev2udev() when a tty was being detached concurrently with the sysctl
handler. One difference relative to 7.x+ is that we still leak tty
objects in tty_free() since destroy_dev() in 6.x doesn't purge all
threads.
