[sheepdog] [PATCH 0/5] add support for upgrading sheepdog from 0.5 to 0.6

[MORITA Kazutaka]

From: MORITA Kazutaka <morita.kazutaka at lab.ntt.co.jp>

Currently, starting sheepdog against an older store will completely
break epoch information.  This series fixes it.

MORITA Kazutaka (5):
  sheep: don't use journal for epoch write
  migrate: add helper to calculate file size
  migrate: add helper to do process for each epoch
  migrate: add support for upgrading from v0.5.5 or earlier
  sheep: check store format at compile time
