I'm not going into the debate about whether or not deprecating one tunable 
for two years is sufficient or not. I'm simply going to mention one app 
that I know of that needs to be converted to use "oom_score_adj" on my 
box :

[jj@...gon ~]$ uname -a
Linux dragon 2.6.37-rc1-ARCH-00542-g0143832-dirty #1 SMP PREEMPT Mon Nov 15 22:01:52 CET 2010 x86_64 Intel(R) Core(TM)2 Duo CPU T7250 @ 2.00GHz GenuineIntel GNU/Linux
[jj@...gon ~]$ dmesg | grep oom_adj
start_kdeinit (1502): /proc/1502/oom_adj is deprecated, please use /proc/1502/oom_score_adj instead.
[jj@...gon ~]$ /usr/lib/kde4/libexec/start_kdeinit --version

Qt: 4.7.1
KDE: 4.5.3 (KDE 4.5.3)
