However there is a different bug in my patch relating to the last entry
which can have shorter length from the rest. So get_order on the last
entry is incorrect - I have to store the deduced order and carry it over.
Will that work if there is only one entry in the list and if it is a short
entry?
Yeah, needs more work. I especially don't like that case (as in any
other with a final short chunk) wasting memory. So it would need more
refactoring to make it possible.
It did work in my internal tree where sgl_alloc_order was extended to
become sgl_alloc_order_min_max, and as such uses a smaller order for
smaller chunks.
This patch can be dropped for now but the earlier ones are still valid I
think. On those one I think we have some opens on how to proceed so if
you could reply there, where applicable, that would be great.
