Since several bugs with much more details were merged into this one, the most likely early warning of zram problems are messages like
Buffer I/O error on device zram0, logical block 257912 [repeated X times]
You get those right after modprobing / formatting zram. If you don't see those with the new kernel, either things are in good shape or the bugfix didn't work.
