Subject: [PATCH 09/17] Create.c: close mdfd and generate uevent
Git-commit: ce559078a5650afb9f635204b31a89a1fa0061e3
References: jsc#SLE-13700

During mdfd closing change event is not generated because open() is
called before start watching mddevice by udev.
Device is ready at this stage. Unblock device, close fd and
generate event to give a chance next layers to work.
