Ah, well, yes...  ktrace can write a lot to disk.  If you ktrace the
process that forks all the syzkaller processes, that will be a lot of
traced system calls very rapidly!

There are still some bugs I haven't tracked down in ktrace itself that
syzbot found, so it may still be worthwhile to fuzz ktrace somehow,
but whatever this reproducer is doing (haven't looked closely) might
not be worth pursuing further.
