something funny about tty's on 2.6.4-rc1-mm1

[Nuno Monteiro]

Hi all,

I just took 2.6.4-rc1-mm1 for a spin, and there's definitely something  
funny about tty's. I left the computer unattended and had visitors over,  
among them small children who, apparently, decided I needed 350 aterm's  
open ;-). So, after they left I issued a 'killall -9 aterm' and fired up  
a new one, and here's something definitely interesting:

nuno@hobbes:~$ w
18:33:56 up  4:08, 157 users,  load average: 0.03, 0.89, 1.51
USER     TTY        LOGIN@   IDLE   JCPU   PCPU WHAT
nuno     :0        14:26   ?xdm?   3:55   0.95s gnome-session
nuno     pts/358   18:30    0.00s  0.10s  0.00s w


I know for a fact that I don't have 157 logged in users (well, there's  
only 45 processes running right now), and shouldn't pts' be recycled, and  
a lower number be assigned? The last kernel I ran was 2.6.3, and none of  
this happened.

My config is:

CONFIG_UNIX98_PTYS=y
CONFIG_LEGACY_PTYS=y
CONFIG_LEGACY_PTY_COUNT=512

and this is a plain jane static /dev -- not devfs nor udev. Despite the  
supposedly 157 users logged in, /dev/pts only contains '358', which is  
the one allocated to this instance of aterm right now.

nuno@hobbes:~$ ls -l /dev/pts
total 0
crw--w----    1 nuno     users    136, 102 Mar  1 18:41 358

In the mean time I'll fall back to 2.6.3.


Regards,


		Nuno
