Re: [PATCH] mm/mempolicy: add sysfs interface to override NUMA node bandwidth

Hi Gregory,

If userland is setting the raw bandwidth stat, why can't they do a tiny
bit of math to figure out the preferred weighting and just write the
weights?

We're not setting the raw bandwidth stat directly, but overriding
the top-level bandwidth to observe the final effect.

Should be posted as [RFC] then, I don't think we want this upstream.

Thanks for the suggestion.
