Subject: linux-next: manual merge of the akpm-current tree with the tip tree
Date: Mon, 14 Nov 2016 17:08:35 +1100
Message-ID: <20161114170835.0c3726e7@canb.auug.org.au> (raw)

Hi Andrew,

Today's linux-next merge of the akpm-current tree got a conflict in:

  mm/memcontrol.c

between commit:

  308167fcb330 ("mm/memcg: Convert to hotplug state machine")

from the tip tree and commit:

  2558c318449d ("mm: memcontrol: use special workqueue for creating per-memcg caches")

from the akpm-current tree.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging.  You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.

Cheers,
Stephen Rothwell
