Subject: linux-next: manual merge of the block tree with the f2fs tree

Hi Jens,

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

  fs/f2fs/data.c

between commit:

  6d63ed97a1f2 ("f2fs: detect host-managed SMR by feature flag")

from the f2fs tree and commit:

  04d328defd06 ("f2fs: use bio op accessors")

from the block 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
