Hi Andrew,
Today's linux-next merge of the akpm-current tree got a conflict in:
include/linux/dax.h
between commit:
ecdb4bf9e327 ("dax: export a low-level __dax_zero_page_range helper")
from the dax-misc tree and commit:
29d44f6759f6 ("dax: add dax_get_unmapped_area for pmd mappings")
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.
