I got this running ./runltp -x 2, can't recall this happening before. It
bothers me a bit as it's a GFP_KERNEL allocation and there's lots of
swap available. I don't think I've learned to fully decipher these
oom-dumps fully yet (especially the active/inactive stat) but this looks
fishy to me.

Run with /proc/sys/vm/swappiness=1

After the killing /proc/meminfo reports lots of MemFree.
