Oh, I completely forgot about that. You're right of course. I pushed
the for-chris branch again, it now looks like this:

Arne Jansen (6):
      btrfs: add an extra wait mode to read_extent_buffer_pages
      btrfs: add READAHEAD extent buffer flag
      btrfs: state information for readahead
      btrfs: initial readahead code and prototypes
      btrfs: hooks for readahead
      btrfs: use readahead API for scrub
