The old parameters, @ref_generation and @owner_objectid, are pretty
confusing when using auto-completion.

Makes sense and looks good.

Just to remind, did you notice the next function named
btrfs_update_extent_ref() whose parameters contains @ref_generation and
@owner_objectid? This definition was forgotten to be removed in almost
10 years since commit 95d3f20b51e ("Mixed back reference  (FORWARD
ROLLING FORMAT CHANGE)").
This is another business though.
