Subject: linux-next: manual merge of the gfs2 tree with the btrfs tree

Hi all,

Today's linux-next merge of the gfs2 tree got a conflict in:

  fs/gfs2/file.c

between commit:

  39c93b0bf7a6 ("iomap: add per-iomap_iter private data")

from the btrfs tree and commit:

  db0c1968e935 ("gfs2: Variable rename")

from the gfs2 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
