The start argument for btrfs_free_reserved_data_space_noquota() is only used to make sure the amount of bytes we decrement from the bytes_may_use counter of the data space_info object is aligned to the filesystem's sector size. It serves no other purpose. All its current callers always pass a length argument that is already aligned to the sector size, so we can make the start argument go away. In fact its presence makes it impossible to use it in a context where we just want to free a number of bytes for a range for which either we do not know its start offset or for freeing multiple ranges at once (which are not contiguous). This change is preparatory work for a patch (third patch in this series) that makes relocation of data block groups that are not full reserve less data space.
