mdadm/0049-mdadm-move-data_offset-to-struct-shape.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

Subject: [PATCH 49/83] mdadm: move data_offset to struct shape
Data offset is a shape property so move it there to remove additional
parameter from some functions.
