2.6.31-rc4 - slab entry tak_delay_info leaking ???

[Paul Rolland]

Hello,

Since I'm running 2.6.31-rc? (3 or 4 I think), I often find my machine with
my X session killed in the morning, and the kdm login screen displayed.

This morning, I decided to save the /var/log/messages to check it before
rebooting, and saw that the OOM killer triggered during the night.
So, I quickly made a copy of it, and a slabtop output. There came the
surprise : 
  OBJS ACTIVE  USE OBJ SIZE  SLABS OBJ/SLAB CACHE SIZE NAME
12899448 12899445  99%    0.11K 358318       36   1433272K
task_delay_info       

On a freshly booted machine, the same entry shows :
  3204   3191  99%    0.11K     89       36       356K task_delay_info
after the X session is started.

Please find attached the slabtop -o output.

Regards,
Paul
