[Sheepdog] [PATCH v5 0/3] add a blocking callback to cluster notification

[MORITA Kazutaka]

This patchset adds a blocking mechanism to the cluster driver.

Changes from v4 to v5 are:

 - avoid passing an invalid pointer to memcpy() even if the copy size
   is zero

Changes from v3 to v4 are:

 - avoid zero byte memcpy

Changes from v2 to v3 are:

 - make the block_cb() comment clear
 - remove a if statement in switch case to simplify codes

Changes from v1 to v2 are:

 - separate block and unblock events to enum corosync_message_type


MORITA Kazutaka (3):
  cluster/corosync: link corosync events to list before dispatching
    them
  cluster: add blocking mechanism to notification
  sheep: use block_cb for vdi operations
