I like this patch with two minor nitpicks below. Given that it's a mostly
unrelated cleanup I'd also propagate it to the first patch in the

I'd really move this calculation and the comment describing it into a
macro/inline in the header, next to the defintion of struct xfs_buf_log_format.
Also I'd probably rewrite the expressions as:
offsetoff(struct xfs_buf_log_format, blf_map) +
(blf->blf_map_size * sizeof(blf->blf_data_map));
> + * Minimum and maximum blocksize and sectorsize.
> + * The blocksize upper limit is pretty much arbitrary.
> + * The sectorsize upper limit is due to sizeof(sb_sectsize).

While I agree with the move of these constants, what does it have to do
with this patch?
