When triggered by pressing the VSTATUS key or calling the TIOCSTAT
ioctl, the n_tty line discipline will display a message on the user's
tty that provides basic information about the system and an
'interesting' process in the current foreground process group, eg:

   load: 0.58  cmd: sleep 744474 [sleeping] 0.36r 0.00u 0.00s 0% 772k

The status message provides:
  - System load average
  - Command name and process id (from the perspective of the session)
  - Scheduler state
  - Total wall-clock run time
  - User space run time
  - System space run time
  - Percentage of on-cpu time
  - Resident set size

The message is only displayed when the tty has the VSTATUS character
set, the local flags ICANON and IEXTEN are enabled and NOKERNINFO is
disabled; it is always displayed when TIOCSTAT is called regardless of
tty settings.

It looks like my comments were addressed. However you did not document the chances since v1 here. IOW, [v2] tag missing here.

And please add the CCs I added last time, so that relevant people still can comment.

thanks,
