Hi all, This is the second take of a patch that I submitted some time ago for allowing specifying vcpu pinning taking NUMA nodes into account. IOW, something like this: * "nodes:0-3": all pCPUs of nodes 0,1,2,3; Â* "nodes:0-3,^node:2": all pCPUS of nodes 0,1,3; Â* "1,nodes:1-2,^6": pCPU 1 plus all pCPUs of nodes 1,2 ÂÂ but not pCPU 6; v1 was a single patch, this is a small series. It become necessary to do that while coping with the review comments I got from IanJ. While at it, I am also sending a small fix to the xl manpage, which is not related to the series, but is still about vcpu pinning (something that I forgot to change when working on NUMA-aware scheduling), as the first patch in the series itself. I really believe I addressed all of Ian's comments, although, no, I haven't converted the parsing to flex (which was not an hard requirement, AFAIUI), because I don't think it is worthwhile in this case. Let me know what you think about it.
