Andrew, Lee, what's the status of this patchset? I don't see it, or the
mempolicy support version, in mmotm-2009-08-12-13-55.
I think there are use cases for both the per-node hstate attributes and
the mempolicy restricted hugepage allocation support and both features can
co-exist in the kernel.
My particular interest is in the per-node hstate attributes because it
allows job schedulers to preallocate hugepages in nodes attached to a
cpuset with ease and allows node-targeted hugepage freeing for balanced
allocations, which is a prerequisite for effective interleave
optimizations.
I'd encourage the addition of the per-node hstate attributes to mmotm.
Thanks Lee for implementing this feature.
