mdadm/0060-mdadm-replace-container-level-checking-with-inline.patch
Xiao Ni cdf21d08ef Update to latest upstream 
After updating to latest upstream, bug2163711 can be fixed.
We don't use rhel only udev rule anymore and we use the
udev rules from upstream. So we don't need to modify our
rhel only udev rule again.

Resolves: bz#2163711
