BUG_ON(x) generates significantly better code than "if (cond) BUG();" because it's not possible to emit the most optimal code sequences like on powerpc that has conditional traps. That's why. I'm applying these transformations all over the networking as I receive them and I advise that you do so for crypto as well. Thank.
