Hi Cosmin,

In general please add a cover letter to all patches. 
Along with providing some general info and anything you particular
want to highlight, it provides somewhere for others comment on the
whole series + it gives a nice name in patchwork!

I've nothing else to add to what Cosmin said on this patch.
