/* For 'assemble' and 'force' we need to return non-zero if any
* change was made. For others, the return value is ignored.
* Update options are:
* force-one : This device looks a bit old but needs to be included,
* update age info appropriately.
* assemble: clear any 'faulty' flag to allow this device to
* be assembled.
* force-array: Array is degraded but being forced, mark it clean
* if that will be needed to assemble it.
*
* newdev: not used ????
* grow: Array has gained a new device - this is currently for
* linear only
* resync: mark as dirty so a resync will happen.
* name: update the name - preserving the homehost
*
* Following are not relevant for this imsm:
* sparc2.2 : update from old dodgey metadata
* super-minor: change the preferred_minor number
* summaries: update redundant counters.
* uuid: Change the uuid of the array to match watch is given
* homehost: update the recorded homehost
* _reshape_progress: record new reshape_progress position.
