Re: [patch 1/6] mempolicy: convert MPOL constants to enum

That doesn't explicitly say what I was most worried about saying, which
is that those MPOL_* terms have values visible in the kernel's public
API, and it does say more than might be true, and it doesn't explain
why it says what it says.

It kinda looks like an ugly "maybe this will shut Paul up patch
<grin>".  I'd rather leave the code the way it was than add that
comment ... sorry.

Ah - now we get to the real issue ?;).

There would be no need to respin; one could do just as you proposed
doing with the above change, queue a little add-on patch to the
existing set.

Really ... look around the kernel.  I believe you'll see many instances
of enum values being spelled out, even ones that count 0, 1, 2, ...,
in situations where the values are constrained by outside forces.
People really do avoid relying on the default enum behaviour having any
particular numbering.

Whatever ... do as you will.
