      pblk: fix max_io calculation · 9205e449
      Javier González authored
      When calculating the maximun I/O size allowed into the buffer, consider
      the write size (ws_opt) used by the write thread in order to cover the
      case in which, due to flushes, the mem and subm pointers are disaligned
      by (ws_opt - 1). This case currently translates into a stall when
      an I/O of the largest possible size is submitted.
      
      Fixes: f9f9d1ae2c66 ("lightnvm: pblk: prevent stall due to wb threshold")

      block: fix segment calculation for passthrough IO · 05b700ba
      Ming Lei authored
      blk_recount_segments() can be called in bio_add_pc_page() for
      calculating how many segments this bio will has after one page is added
      to this bio. If the resulted segment number is beyond the queue limit,
      the added page will be removed.
      
      The try-and-fix policy requires blk_recount_segments(__blk_recalc_rq_segments)
      to not consider the segment number limit. Unfortunately bvec_split_segs()
      does check this limit, and causes small segment number returned to
      bio_add_pc_page(), then page still may be added to the bio even though
      segment number limit becomes broken.
      
      Fixes this issue by not considering segment number limit when calcualting
      bio's segment number.
      
      Fixes: dcebd755 ("block: use bio_for_each_bvec() to compute multi-page bvec count")
