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

Hi all,

Today's linux-next merge of the btrfs tree got conflicts in:

  fs/btrfs/inode.c
  fs/btrfs/space-info.c

between commits:

  3d45f221ce62 ("btrfs: fix deadlock when cloning inline extent and low on free metadata space")
  e076ab2a2ca7 ("btrfs: shrink delalloc pages instead of full inodes")

from the btrfs-fixes tree and commits:

  50f2ad0e64bd ("btrfs: fix deadlock when cloning inline extent and low on free metadata space")
  123b5509410e ("btrfs: track ordered bytes instead of just dio ordered bytes")

from the btrfs tree.

I fixed it up (I used the former version of the conflicts in inode.c
and 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.
