This series introduces cache options 'page', which uses a page cache
on storage nodes for vdi cache, and 'unsafe', which doesn't sync at

'page' is useful when VMs are running on different cluster from sheeps
and we can use a lot of memory on sheep nodes for a Sheepdog VDI

'unsafe' is useful when a datacenter can provide a reliable power and
we are unlikely to lose in-memory data.  We can also use this option
for testing purpose.

MORITA Kazutaka (2):
  sheep: add cache option 'page' to use page cache on storage nodes
  sheep: add cache option 'unsafe' to disable sync
