Subject: linux-next: manual merge of the akpm-current tree with the
 aio-direct tree

Hi Andrew,

Today's linux-next merge of the akpm-current tree got a conflict in
mm/shmem.c between commit b080082bc3e8 ("tmpfs: add support for read_iter
and write_iter") from the aio-direct tree and commit c6dc71ff08f7 ("mm:
drop actor argument of do_shmem_file_read()") from the akpm-current tree.

I fixed it up (see below) and can carry the fix as necessary (no action
is required).

Cheers,
Stephen Rothwell                    sfr@...b.auug.org.au
