As you were on th patch delivery path, all of these patches should have your Signed-off-by:. But some were missing it. I fixed this in my copy of the patches. I suspect this patchset adds a significant amount of code which will not be used if CONFIG_MEMORY_HOTPLUG=n. "[PATCH v6 06/15] memory-hotplug: implement register_page_bootmem_info_section of sparse-vmemmap", for example. This is not a good thing, so please go through the patchset (in fact, go through all the memhotplug code) and let's see if we can reduce the bloat for CONFIG_MEMORY_HOTPLUG=n kernels. This needn't be done immediately - it would be OK by me if you were to defer this exercise until all the new memhotplug code is largely in place. But please, let's do it. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx. For more info on Linux MM, see: http://www.linux-mm.org/ .
