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

Hi all,

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

  fs/ext4/file.c

between commit:

  c37683e32cca ("ext4: add more robust reporting of metadata writeback errors")

from the file-locks tree and commit:

  728fbc0e10b7 ("ext4: nowait aio support")

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
