mdadm/mdadm-3.2.3-simplify-calculating-array_blocks.patch
Jes Sorensen 6148d71c1d Fix a large number of bzs:
- Fix Monitor mode sometimes crashes when a resync completes
- Fix missing symlink for mdadm container device when incremental creates
  the array
- Make sure when creating a second array in a container that the second
  array uses all available space since leaving space for a third array
  is invalid
- Validate the number of imsm volumes per controller
- Fix issues with imsm arrays and disks larger than 2TB
- Add support for expanding imsm arrays/containers
- The support for expanding imsm arrays/containers was accepted upstream,
  update to the official patches from there
- Fix for the issue of --add not being very smart
- Fix an issue causing rebuilds to fail to restart on reboot (data
  corrupter level problem)
- Reset the bad flag on map file updates
- Correctly fix failure when trying to add internal bitmap to 1.0 arrays

Subject: [PATCH 3/7] simplify calculating array_blocks
no point calling info_to_blocks_per_member when it just returns size*2 for level==1
calc_array_size can be used for all levels
