mm: writeback: cleanups in preparation for per-zone dirty limits
The next patch will introduce per-zone dirty limiting functions in addition to the traditional global dirty limiting. Rename determine_dirtyable_memory() to global_dirtyable_memory() before adding the zone-specific version, and fix up its documentation. Also, move the functions to determine the dirtyable memory and the function to calculate the dirty limit based on that together so that their relationship is more apparent and that they can be commented on as a group.
