A little utility that would cause a lot of work to keep up to date when the kernel can already give you the bare numbers you need? We have tools for sysadmins that collect these numbers and present a higher level overview but that does not help us. If they report a problem then you have to dig down into where this information come from to figure out what is wrong. > > The cpu affinity is a horror to see on 4096 cpu systems.

But it summarizes various things and so it is mostly useless baggage if you are debugging a kernel problem. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
