[PATCH v3 0/2] Fixup for discontiguous/sparse numa nodes

2017-08-21 Thread sathnaga
From: Satheesh Rajendran Certain systems would have sparse/discontinguous numa nodes. perf bench numa doesnt work well on such nodes. 1. It shows wrong values. 2. It can hang. 3. It can show redundant information for non-existant nodes. #numactl -H available: 2 nodes (0,8) node 0 cpus: 0 1 2 3
