I finally got around to retest it.
total fragmenting movable fragmenting&&movable
base-1: 957 583 353 0
base-2: 2715 2343 359 0
base-3: 2033 1669 353 0
patched-1: 1325 929 371 0
patched-2: 2844 2451 371 0
patched-3: 1304 917 361 0
fragmenting=1 is defined as fallback_order<pageblock_order which is most
of them.
Patched kernel showed slightly elevated movable(fallback_migratetype=1)
cases. Is it critical?
There's no allocations that is fragmenting and movable. Hm.
