Subject: linux-next: manual merge of the net-next tree with the mm tree
Hi all,
Today's linux-next merge of the net-next tree got a conflict in:
include/linux/slab.h
between commit:
7bd230a26648 ("mm/slab: enable slab allocation tagging for kmalloc and friends")
from the mm_unstable branch of the mm tree and commit:
a1d6063d9f2f ("slab: introduce kvmalloc_array_node() and kvcalloc_node()")
from the net-next tree.
I fixed it up (maybe? 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
