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
