Hi Marek,
One minor thing - please use a cover letter.
Provides an obvious place for me to reply when picking things up and
gives the whole series a meaningful title in patchwork.
Anyhow, looks straight forward to me so I'll apply it to my current testing
tree. Not that will get rebased on rc1 once available.
If anyone has additional feedback in the meantime I'm happy to rebase
until this gets pushed out as togreg so can add tags or make other changes.
Thanks,
Jonathan
