[sheepdog] [PATCH stable-0.7 0/3] update for vdi checking on nr_zones < inode->nr_copies

[Hitoshi Mitake]

This update is a bugfix for "dog vdi check". When "dog vdi check" is invoked in
an environment with a number of zones which is less than inode->nr_copies, the
command rised panic. This update fixes this problem.

This update contains manual modification for backporting. If no one disagrees in
2 days or a maintainer agrees, it will be pushed to stable-0.7.

Hitoshi Mitake (3):
  tests/functional: add a new test for vdi check with the condition
    nr_zones < inode->nr_copies
  dog: caliculate a number of zones
  dog: use a minimum number of copies and zones for vdi checking
