 [...]

And those objects are consuming ~2.3GB of slab on your 4GB machine and 
seems to only have occurred between v3.4.2 to v3.5.3.

It would be interesting to see what kmemleak would tell us.

As the Archlinux kernel does not support kmemleak:

[8:04] brief:android-apk% zgrep -i meml /proc/config.gz                
CONFIG_INPUT_FF_MEMLESS=m
# CONFIG_DEBUG_KMEMLEAK is not set

I'll give the latest kernel tree from Linus a try this evening and if it
is in there. If not, I'll go back to 3.5.4 in Linus tree and try again.

Cheers,

Nico
