Fine by me as well, FWIW. My points about per-cpu/node queues were not to say that I'm really opposed to getting this in first. In a way, you sell yourself short with the patch name: the implementation may be just a basic one, but simplicity is a key point of SLOB... Adding numa awareness to the slob APIs is obviously a key step and makes it much easier to experiment with enhancements to the implementation. Unless it has been picked up already, I'd call it "initial NUMA support" ;) Thanks! Would be great to hear about your experiences using SLOB as well -- how much memory you're saving, how it performs, etc. -- SUSE Labs, Novell Inc. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
