Hello Michal, I got the below email few days back. Do I still need to resubmit the patch? or is it already on the way to merge?

Its filename is memory_hotplug-free-pages-as-higher-order.patch This patch should soon appear at http://ozlabs.org/~akpm/mmots/broken-out/memory_hotplug-free-pages-as-higher-order.patch and later at http://ozlabs.org/~akpm/mmotm/broken-out/memory_hotplug-free-pages-as-higher-order.patch Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next and is updated there every 3-4 working days
