      block: Introduce new bio_split() · 20d0189b
      Kent Overstreet 提交于
      The new bio_split() can split arbitrary bios - it's not restricted to
      single page bios, like the old bio_split() (previously renamed to
      bio_pair_split()). It also has different semantics - it doesn't allocate
      a struct bio_pair, leaving it up to the caller to handle completions.
      
      Then convert the existing bio_pair_split() users to the new bio_split()
      - and also nvme, which was open coding bio splitting.
      
      (We have to take that BUG_ON() out of bio_integrity_trim() because this
      bio_split() needs to use it, and there's no reason it has to be used on
      bios marked as cloned; BIO_CLONED doesn't seem to have clearly
      documented semantics anyways.)

      block: Generic bio chaining · 196d38bc
      Kent Overstreet 提交于
      This adds a generic mechanism for chaining bio completions. This is
      going to be used for a bio_split() replacement, and it turns out to be
      very useful in a fair amount of driver code - a fair number of drivers
      were implementing this in their own roundabout ways, often painfully.
      
      Note that this means it's no longer to call bio_endio() more than once
      on the same bio! This can cause problems for drivers that save/restore
      bi_end_io. Arguably they shouldn't be saving/restoring bi_end_io at all
      - in all but the simplest cases they'd be better off just cloning the
      bio, and immutable biovecs is making bio cloning cheaper. But for now,
      we add a bio_endio_nodec() for these cases.

      various drivers would choke on such things. But with immutable biovecs
      and our new bio splitting that shares the biovecs, submitting partially

      bcache: Kill unaligned bvec hack · ed9c47be
      Kent Overstreet 提交于
      Bcache has a hack to avoid cloning the biovec if it's all full pages -
      but with immutable biovecs coming this won't be necessary anymore.
      
      For now, we remove the special case and always clone the bvec array so
      that the immutable biovec patches are simpler.

      block: Convert various code to bio_for_each_segment() · 2c30c71b
      Kent Overstreet 提交于
      With immutable biovecs we don't want code accessing bi_io_vec directly -
      the uses this patch changes weren't incorrect since they all own the
      bio, but it makes the code harder to audit for no good reason - also,
      this will help with multipage bvecs later.

          accidently copy uninitialized memory back into userspace and also
          make sure that we never try to use more that sockaddr_storage for
          building the on-kernel-stack copy of a sockaddr.  Fixes from Hannes
