This approach aims to retain the current behavior of load balancer with the change being only in the metric consumed during load balancing, without unnecessary introduction of new variables.This RFC has been posted to evaluate its design;to see if this is the right way to go about introducing per-entity-load-tracking metric for the consumers of the same; in this specific case,the load balancer.Once the design has been approved off,I can go around to testing it.
The patch has been based out of tip-master:HEAD at commit 8a1d31c703d Subject:Merge branch 'x86/urgent'
Grateful to Peter Zijlstra and Ingo Molnar for their valuable feedback on v1 of the RFC which was the foundation for this version.
PATCH[1/2] Aims at enabling usage of Per-Entity-Load-Tracking for load balacing PATCH[2/2] The crux of the patchset lies here. ---
