This patch-set aims to implement physical memory hot-removing.
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.
Thank you very much for the help. Next time I'll add it myself.
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.
OK, I'll do have a check on it when the page_cgroup problem is solved.
Thanks. :)
