v2:
- rebased on top of my patch 'remove sd_*_req and sd_*_rsp'
- fix SD_RES_NO_VDI error
- add test
This series makes sheep return SD_RES_READONLY when write requests are
sent to the snapshot data objects, and notifies the running VMs that
they need to reload the vdi objects.
MORITA Kazutaka (6):
move vdi_is_snapshot() to sheepdog_proto.h
sheep: make oid_to_vid support any kind of objects
sheep: store snapshot vid information in memory
sheep: return SD_RES_READONLY when write requests are sent to
snapshots
sheep: make SD_OP_GET_INFO a cluster operation
tests: add test to check live snapshot
