The hugetlb parameters parsing is a bit mess but this at least makes it
behave more consistently. Feel free to add to all patches
Acked-by: Michal Hocko <mhocko@...e.com>

On a side note. I have received patches with broken threading - the
follow up patches are not in the single thread under this cover email.
I thought this was the default behavior of git send-email but maybe your
(older) version doesn't do that. --thread option would enforce that
(with --no-chain-reply-to) or you can set it up in the git config. IMHO
it is always better to have the patchset in the single email thread.
