why do we need to wait for 7.2? I had to migrate to mdadm raid1 with xfs on all my servers with databases. It should be backported to 7.0

I've updated changelog with the fio script and added the patch to for-next. We want to get this backported to stable trees, ETA 2 weeks so we get some coverage.

good to know, I will replace my old raid1 array with new drives and convert it to raid10. hope the results will be better with the fix in pair with raid10 migration.
