[sheepdog] [PATCH 0/9] don't let new nodes commit suicide when joining a cluster in WAIT_FOR_JOIN state V2

[Christoph Hellwig]

This series allows to start new sheep when the cluster is in WAIT_FOR_JOIN
status.  They still don't count towards the number of required old sheep,
but will join the cluster as soon as old sheep have been seen.

Changes since v1 (with a different title) are only minor coding style fixups.
