Subject: linux-next: manual merge of the akpm-current tree with the hmm tree
Date: Thu, 4 Jul 2019 20:09:56 +1000 [thread overview]
Message-ID: <20190704200956.016f2297@canb.auug.org.au> (raw)
[-- Attachment #1: Type: text/plain, Size: 2748 bytes --]
Hi all,
Today's linux-next merge of the akpm-current tree got a conflict in:
include/linux/mm.h
between commit:
25b2995a35b6 ("mm: remove MEMORY_DEVICE_PUBLIC support")
from the hmm tree and commit:
0a470a2d114a ("mm: clean up is_device_*_page() definitions")
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
