      block: convert bio_copy_user to bio_copy_user_iov · c5dec1c3
      FUJITA Tomonori 提交于
      This patch enables bio_copy_user to take struct sg_iovec (renamed
      bio_copy_user_iov). bio_copy_user uses bio_copy_user_iov internally as
      bio_map_user uses bio_map_user_iov.
      
      The major changes are:
      
      - adds sg_iovec array to struct bio_map_data
      
      - adds __bio_copy_iov that copy data between bio and
      sg_iovec. bio_copy_user_iov and bio_uncopy_user use it.

      fs/block_dev.c: remove #if 0'ed code · 86b6c7a7
      Adrian Bunk 提交于
      Commit b2e895db #if 0'ed this code stating:
      
      <--  snip  -->
      
          [PATCH] revert blockdev direct io back to 2.6.19 version
      
          Andrew Vasquez is reporting as-iosched oopses and a 65% throughput
          slowdown due to the recent special-casing of direct-io against
          blockdevs.  We don't know why either of these things are occurring.
      
          The patch minimally reverts us back to the 2.6.19 code for a 2.6.20
          release.
      
      <--  snip  -->
      
      It has since been dead code, and unless someone wants to revive it now
      it's time to remove it.
      
      This patch also makes bio_release_pages() static again and removes the
      ki_bio_count member from struct kiocb, reverting changes that had been
      done for this dead code.

      Drop 'size' argument from bio_endio and bi_end_io · 6712ecf8
      NeilBrown 提交于
      As bi_end_io is only called once when the reqeust is complete,
      the 'size' argument is now redundant.  Remove it.
      
      Now there is no need for bio_endio to subtract the size completed
      from bi_size.  So don't do that either.
      
      While we are at it, change bi_end_io to return void.

      Don't decrement bi_size in bio_endio · 5bb23a68
      NeilBrown 提交于
      The only caller of bio_endio that does not pass the full bi_size
      is end_that_request_first.  Also, no ->bi_end_io method is really
      interested in bi_size being decremented.
      
      So move the decrement and related code into ll_rw_blk and merge it
      with order_bio_endio to form req_bio_endio which does endio functionality
      specific to request completion.
      
      As some ->bi_end_io methods do check bi_size of 0, we set it thus for
      now, but that will go in the next patch.

      Only call bi_end_io once for any bio · 9cc54d40
      NeilBrown 提交于
      Currently bi_end_io can be called multiple times as sub-requests
      complete.  However no ->bi_end_io function wants to know about that.
      So only call when the bio is complete.
