[Liu Yuan]

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

v3:
 - continue process when get_path_size() fails in md_get_info()
 - strlen correction in collie node md command
 - comment correction

v2:
 - fix object stale purging for md

This is the final part for MD. With this patch set, We even allow group plug, 
group unplug and disks/node failure during (un)plugging.

Also add disk information function for collie.

Liu Yuan (6):
  tests/055: test simultaneous multiple disk failures on the same node
  net: enlarge connect_to_addr() scope
  md: add hot-plug and hot-unplug support
  collie: add new commands to manipulate multi-disks
  sheep: remove duplicate recovery complete notification
  tsets: add 057 to test md hot-plug and hot-unplug
