Yes, absolutely. We should be able to deal with swap-less systems. The
patch to fix this is probably very easy (just look for ENOENT when we
open /proc/swaps and consider it not an error, plus some checking for
m->proc_swaps here and there). I have now added this to the TODO
list. However, since I do not run kernels like this here I won't be able
to test this and hence am unlikely to fix this anytime soon. However,
I'd be happy to merge a patch if you (or somebody else) supply one.
