Hm, not sure if it was from the patch or what but I ran this:

1. swapoff -a
2. ./eatmem


You usually have to access the allocated memory, like:

*d = 1.0;

for it to actually be allocated (AFAIK).

}

return 0;
}

Any idea why the OOM killer can or does not kill it?

What are the values of /proc/sys/vm/overcommit* ?

See Documentation/vm/overcommit-accounting .

They should be the defaults as I do not change them:

p34:~# find /proc/|grep -i overcommit
/proc/sys/vm/overcommit_memory
/proc/sys/vm/overcommit_ratio
find: /proc/5128: No such file or directory
p34:~# cat /proc/sys/vm/overcommit_memory
0
p34:~# cat /proc/sys/vm/overcommit_ratio
50
p34:~#
