I kept the '!= 0' only because that is the preferred FreeBSD style. Note that one could rewrite this assertion as:

if ((xa->flags & XA_FLAGS_ALLOC1) != 0)
    MPASS(mask > 1);

Not sure if that would be more readable?

We also want to assert mask > 0 for xa->flags & XA_FLAGS_ALLOC1 == 0 though do we not?

Hmmm, I had misread as it as being tautological (>= 0).
