Subject[RFC] ext2_new_block() behaviour
	Folks, there is a pretty strange detail of the allocation policy -
if cylinder group has no free blocks past the goal ext2 tries very hard to
avoid allocation in the beginning of the group. I.e. order looks so:

* goal
* goal .. (goal+63) & ~63
* goal .. end of cylinder group
* cylinder groups past one that contains goal
* cylinder groups before one that contains goal
* beginning of cylinder group..goal-1

It looks somewhat fishy. What's the reason for such policy?
Cheers,
Al
