In the Linux kernel, the following vulnerability has been resolved: block: fix adding folio to bio >4GB folio is possible on some ARCHs, such as aarch64, 16GB hugepage is supported, then offset of folio cant be held in unsigned int, cause warning in bio_add_folio_nofail() and IO failure. Fix it by adjusting page & trimming offset so that `->bi_offset` wont be overflow, and folio can be added to bio successfully.
