From: Dave Chinner <dgc@sgi.com>

Note that there are many > 80 char lines introduced due to the
xfs_btree_key casts. But the places where this happens is throw-away code
once the whole btree code gets merged into a common implementation.

The same is true for the temporary xfs_alloc_log_keys define to the new
name. All old users will be gone after a few patches.

[hch: split out from bigger patch and minor adaptions]
