 It's not that obvious - apparently the intended device name is
 "/dev/device0.lfs" and "/dev/rdevice0.lfs".
 That said, I don't see anything obvious in tests/fs where the string
 'rumpfs' would be coming from. (The extra 'r' is for the raw device;
 assuming the problem isn't some other fs jumping into the lfs code, it
 appears that ta_devpath[] in struct lfstestargs has gotten "rumpfs" in
 it, somehow.
 Conversely the problem could be that something's jumping into the lfs
 test code from a different fs, somehow, and something else unrelated
 is appearing in the later fields of struct lfstest args.
 Figuring out which test triggers it would be helpful.
