This feels like it's a comment on an entirely different patch, like this one: https://git.infradead.org/users/willy/pagecache.git/commitdiff/fe9841debe24e15100359acadd0b561bbb2dceb1 bio_limit() doesn't guess anything, it just clamps the argument to BIO_MAX_PAGES (which is itself misnamed; it's BIO_MAX_SEGS now)
