Oh, sorry for that.

Actually, i tried your suggestion however i noticed it makes the code
little confuse, as we construct the fit by calling
nvdimm_build_device_structure() whose name shows the fit will be
rebuild but do not set .dirty in the init path.

g_array_new(false, true /* clear */, 1) is a more clear way to
show this is just a empty array.
