Subject: linux-next: manual merge of the btrfs-kdave tree with Linus' tree

Hi David,

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

  fs/btrfs/extent_io.c

between commit:

  09cbfeaf1a5a ("mm, fs: get rid of PAGE_CACHE_* and page_cache_{get,release} macros")

from Linus' tree and commit:

  a7424783a24d ("Btrfs: make mapping->writeback_index point to the last written page")

from the btrfs-kdave 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
