mdadm/mdadm-3.2.3-Manage-replace-return-1-with-goto-abort.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
- Resolves: bz817023 (f17) bz817024 (f17) bz817026 (f17) bz817028 (f17)
- Resolves: bz817029 (f17) bz817032 (f17) bz817038 (f17) bz808774 (f17)
- Resolves: bz817039 (f17) bz817042 (f17)
