Hm, I don't know why this code wasn't in my copy. Was it already
propagated to Linus' tree? When will it be? Which tree I should merge
from to get your latest fixes?
My code avoided counting metadata blocks (the ones holding the pointers
to actual blocks in indirect, double-indirect and triple-indirect
chains). I thought that i_blocks doesn't take into account the
metablocks but quick experiment with NetBSD image proved me wrong. So I
retract this patch altogether.
My UFS file size limit patch remains though.
