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?

Regards,
Arun

The patch titled
      Subject: mm/page_alloc.c: memory hotplug: free pages as higher 
order
has been added to the -mm tree.  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
