linux-next: manual merge of the block tree with the ext4 tree

[Stephen Rothwell <sfr@canb.auug.org.au>]

Hi Jens,

Today's linux-next merge of the block tree got a conflict in
fs/ext4/fsync.c between commit a68513a1c88248ee9167a25e32ee8164c3dde02b
("ext4: check missed return value in ext4_sync_file()") from the ext4
tree and commit fbd9b09a177a481eda256447c881f014f29034fe ("blkdev:
generalize flags for blkdev_issue_fn functions") from the block tree.

Just context changes.  I fixed it up (see below) and can carry the fix as
necessary.
