• 2ec3182f9   Documentation: update notes in biovecs about arbitrarily sized bios ... Browse Code »

  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.

  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.
