- typo in write_mostly constructor argument
- function argument types
- recovery ad raid set size issues 
- out-of-place reshape offset checks
- reject resize during reshape
- enhance reshape checks
- avoid memory leaks in destructor
- comment typos and enhancements

Please review and schedule for 4.8 inclusion

Done, just cleaned up the headers a bit and folded 2 comment specific
patches.

Now staged in linux-next (via linux-dm.git's 'for-next') for 4.8
inclusion.
