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...

This patchset follows the main idea discussed at 2012 LSFMMS section: "Ballooning for transparent huge pages" -- http://lwn.net/Articles/490114/ to introduce the required changes to the virtio_balloon driver, as well as changes to the core compaction & migration bits, in order to allow memory balloon pages become movable within a guest. Rafael Aquini (4): mm: introduce compaction

From: Gioh Kim <gurugio at hanmail.net> Hello, This series try to enable migration of non-LRU pages, such as driver's page. My ARM-based platform occured severe fragmentation problem after long-term (several days) test. Sometimes even order-3 page allocation failed. It has memory size 512MB ~ 1024MB. 30% ~ 40% memory is consumed for graphic processing and 20~30 memory is reserved for
