Except that this bug can eat filesystems, so making it more likely will cause more filesystems to be eaten. Anyway, whether we go for 4k in 2.6 or not, we should do our best to fix bad code and I will go looking for some more so others can go and fix some more. There's still enough horror in mainline for more than one amusement park, we just haven't found it yet. Jörn -- All art is but imitation of nature. -- Lucius Annaeus Seneca
