[sheepdog] [PATCH 0/2] add cache options 'page' and 'unsafe'

[MORITA Kazutaka]

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

'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
cache.

'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
