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. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org. For more info on Linux MM, see: http://www.linux-mm.org/ .
