[PATCH 0/4] Prepare mdadm for migrations (external meta)

[Adam Kwolek <adam.kwolek@intel.com>]

This few patches prepares mdadm for level and chunk size migration using external metadata.
1. FIX: delta_disk can have UnSet value
  A while ago I've reported problem that delta_disks can have UnSet value, so adding it
  to raid_disks can produce error in mdadm. Looking my first patch you proposed
  to address this problem by changing reshape_super() interface rather than
  set condition on function call. This patch implements your idea.

2. FIX: Get spares from external metadata
   imsm: FIX: Add spare disks information to array description
  Those 2 patches addresses problem with not initializes spares counter in mdinfo
  using external metadata.

3. FIX: Add raid5 to raid0 case to analyse_change()
  This patch adds missing of level transition in Grow.c

This series should be applied on devel-3.2 branch with my yesterday's 4 patches
