Yeah, the first patch from Neil renames a function (as its subject says) and the
second patch from me converts most of its users to new helpers specific to the
PF_MEMALLOC flags.

Hmm I could redo my patch on top of Neil's patch, but then Andrew would have to
carry Neil's patch as well just to have a working mmotm? And then make sure to
send my patch (but not Neil's) only after the tip tree is pulled? Would that
work for the maintainers involved?

I see two remaining instances of current_restore_flags(). One in __do_softirq()
is even for PF_MEMALLOC, but there the flag is cleared first and then set back,
which is opposite of the common case that my helpers provide. The other in nfsd
is for PF_LESS_THROTTLE which is not common enough to earn own helpers yet. IIRC
Neil originally wanted to add a new one?
