Agreed.
We never noticed because it can trigger only if there's been an I/O error
while reading the group stuff in memory (and the probability to have an
I/O error exactly in such place is very low). Also it seems to me that
even if it triggers it won't cause subtle silent corruption but it will
more safely generate immediatly an Oops inside ext2fs. It was probably
hurting a bit performances in some case (because we was probably entering
load__block_bitmap more than necessary ;).
Thanks.
