Subject: linux-next: build failure after merge of the block tree

Hi Jens,

After merging the block tree, today's linux-next build (x86_64
allmodconfig) failed like this:

fs/f2fs/data.c: In function 'submit_read_page':
fs/f2fs/data.c:457:10: error: 'struct bio' has no member named 'bi_sector'
   io->bio->bi_sector = SECTOR_FROM_BLOCK(sbi, blk_addr);
          ^

Caused by commit 4f024f3797c4 ("block: Abstract out bvec iterator") from
the block tree interacting with commit 32cd69ef0893 ("f2fs: add a new
function to support for merging contiguous read") from the f2fs tree.

I added the following merge fix patch:
