      block: bounce: make sure that bvec table is updated · 8f4e80da
      Ming Lei authored
      Block bounce needs to allocate new page for doing IO, and the
      new page has to be updated to bvec table.
      
      Commit 6dc4f100 switches __blk_queue_bounce() to use the new
      bio_for_each_segment_all() interface. Unfortunately the new
      bio_for_each_segment_all() can't be used to update bvec table.
      
      This patch fixes this issue by retrieving bvec from the table
      directly, then the new allocated page can be updated to the bio.
      This way is safe because the cloned bio is single page bvec.
      
      Fixes: 6dc4f100 ("block: allow bio_for_each_segment_all() to iterate over multi-page bvec")

      nvme-rdma: use nr_phys_segments when map rq to sgl · 34e08191
      Chaitanya Kulkarni authored
      Use blk_rq_nr_phys_segments() instead of blk_rq_payload_bytes() to check
      if a command contains data to be mapped.  This fixes the case where
      a struct request contains LBAs, but it has no payload, such as
      Write Zeroes support.
      
      Fixes: 6e02318e ("nvme: add support for the Write Zeroes command")
