[lvm-devel] [PATCH mirror 3/13] Enable layer specification in remove_layer_from_lv()

[Jun'ichi Nomura]

Added layer_lv argument to remove_layer_from_lv().

remove_layer_from_lv() has implicitly removed the top-most layer.
It won't work if the layer can be stacked.
The caller knows which layer it wants to remove.

find_parent_for_layer() will help find a parent LV for specified layer LV.

Thanks,
