       "This is a bit bigger than it should be, but I could (did) not want to
        send it off last week due to both wanting extra testing, and expecting
        a fix for the bounce regression as well.  In any case, this contains:
      
         - Fix for the blk-merge.c compilation warning on gcc 5.x from me.
      
         - A set of back/front SG gap merge fixes, from me and from Sagi.
           This ensures that we honor SG gapping for integrity payloads as
           well.
      
         - Two small fixes for null_blk from Matias, fixing a leak and a
           capacity propagation issue.
      
         - A blkcg fix from Tejun, fixing a NULL dereference.
      
         - A fast clone optimization from Ming, fixing a performance
           regression since the arbitrarily sized bio's were introduced.

      fs-writeback: unplug before cond_resched in writeback_sb_inodes · 590dca3a
      Chris Mason authored
      Commit 505a666e ("writeback: plug writeback in wb_writeback() and
      writeback_inodes_wb()") has us holding a plug during writeback_sb_inodes,
      which increases the merge rate when relatively contiguous small files
      are written by the filesystem.  It helps both on flash and spindles.
      
      For an fs_mark workload creating 4K files in parallel across 8 drives,
      this commit improves performance ~9% more by unplugging before calling
      cond_resched().  cond_resched() doesn't trigger an implicit unplug, so
      explicitly getting the IO down to the device before scheduling reduces
      latencies for anyone waiting on clean pages.
      
      It also cuts down on how often we use kblockd to unplug, which means
      less work bouncing from one workqueue to another.
      
      Many more details about how we got here:
