| 2015-08-13 | Documentation: update notes in biovecs about arbitrarily sized bios | Dongsu Park | |
| Update block/biovecs.txt so that it includes a note on what kind of effects arbitrarily sized bios would bring to the block layer. Also fix a trivial typo, bio_iter_iovec.

| 2013-11-23 | block: Immutable bio vecs | Kent Overstreet | |
| This adds a mechanism by which we can advance a bio by an arbitrary number of bytes without modifying the biovec: bio->bi_iter.bi_bvec_done indicates the number of bytes completed in the current bvec. Various driver code still needs to be updated to not refer to the bvec directly before we can use this for interesting things, like efficient bio splitting.
