kernel BUG at linux-4.10.0 swapops.h

Log attached.

I've seen the 4.10 kernel crash at least twice (on two different machines) apparently when trying to handle swap. The system slows down at first and commands like "ps xa" lock up, then the system completely locks up (I couldn't even access a terminal via CTRL-ALT-F1 etc when it happened just now).

Note that I have swap partitions rather than swapfiles because I'm running btrfs, which doesn't support a swapfile.
