The following series continues OLCE implementation for external metadata.
Main changes:
- Raid0 OLCE is possible
- OLCE for container with 2 arrays works (imsm)
- Spares can be added to raid5 container (roll back of some changes)
- some bugs fixed
Problems:
- checkpointing sometimes hangs
reshape in md is finished, but mdadm stops responding before size set is executed,
somewhere in child_monitor()
- when second array in container is raid0, it is not reshaped during OLCE
for imsm no one at this moment can update metadata:
- mdadm is decided not to do this
- mdmon is not running for this array yet (array_set_state() cannot be called for metadata update)
- mdmon can be run later in reshape_array(), but we need meta update earlier to get reshape_active variable updated

Adam Kwolek (9):
imsm: Proceed with second array reshape only for frozen container
FIX: container has to be frozen during reshape
imsm: FIX: monitor should initialize 2nd reshape only
imsm: FIX: container content gathering is not needed for size set
imsm: Update metadata for second array
imsm: FIX: only one spare is passed in update
imsm:FIX: one spare can be added to raid0 only
FIX: Cannot add spare to monitored container
imsm: FIX: set correct slot information in metadata (raid0)
