[sheepdog] [PATCH 0/5] retire old journal implementation

[Liu Yuan]

From: Liu Yuan <tailai.ly at taobao.com>

This patch set aims to retire old journal.c and rename journal_file.c
as journal.c to get a uniform journaling for object, config file and 
epoch file (this is a future work).

This is because old journal.c can't handle following case:
 1 creat()
 2 *crash*
 3 write()

This will leave an empty file created. Journal file implementation won't have
this problem because it logs create and write as one transaction.

Liu Yuan (5):
  sheep: teach journal file to be md friendly
  tests/047: add md test support
  sheep: teach journal file to handle epoch and config write
  sheep: use new journal API for config file
  sheep: rename journal_file.c as journal.c
