Zsmalloc is ready for page migration so zram can use __GFP_MOVABLE from
now on.
I did test to see how it helps to make higher order pages. Test
scenario is as follows.
KVM guest, 1G memory, ext4 formated zram block device,
for i in `seq 1 8`;
do
dd if=/dev/vda1 of=mnt/test$i.txt bs=128M count=1 &
done
wait `pidof dd`
for i in `seq 1 2 8`;
do
rm -rf mnt/test$i.txt
done
fstrim -v mnt
echo "init"
cat /proc/buddyinfo
echo "compaction"
echo 1 > /proc/sys/vm/compact_memory
cat /proc/buddyinfo
old:
init
Node 0, zone DMA 208 120 51 41 11 0 0 0 0 0 0
Node 0, zone DMA32 16380 13777 9184 3805 789 54 3 0 0 0 0
compaction
Node 0, zone DMA 132 82 40 39 16 2 1 0 0 0 0
Node 0, zone DMA32 5219 5526 4969 3455 1831 677 139 15 0 0 0
new:
init
Node 0, zone DMA 379 115 97 19 2 0 0 0 0 0 0
Node 0, zone DMA32 18891 16774 10862 3947 637 21 0 0 0 0 0
compaction
Node 0, zone DMA 214 66 87 29 10 3 0 0 0 0 0
Node 0, zone DMA32 1612 3139 3154 2469 1745 990 384 94 7 0 0
As you can see, compaction made so many high-order pages. Yay!
