In our use scenario, we want to use DM thinp for a lot of containers as
rootfs. The container use heavy on snapshots,
so above 4K thin/snapshots LVs may share the thin pool concurrently.

This may make the space fragmented. So, another concern is, will using
striped thinp make
fragmentation much more worse?
