If you define virtual NUMA node with Besides mixing virtual/physical, IMHO it will be hairy as the ckrm class needs to have all the zones that exists in the system(unlike the real NUMA node), and it will get more complicated when CKRM is deployed in a NUMA system itself. > some memory and some virtual CPUs, you can just assign target jobs > to them. > > What do you think of my idea? > > Thanks, > Hirokazu Takahashi. > > > I am looking for improvement suggestions > > - to not have a field in the page data structure for the mem > > controller > > - to make vmscan.c cleaner. -- ---------------------------------------------------------------------- Chandra Seetharaman | Be careful what you choose.... - sekharan@us.ibm.com | .......you may get it. ---------------------------------------------------------------------- -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
