      pagemap: Use pread to read pagemap entries · 593cb59a
      Pavel Emelyanov authored
      When reading pagemaps, we read it from specific position. To
      do it, we called lseek, then read. Fortunetely, there's a
      syscall that does both things in one call -- pread. Since
      we don't need to keep pagemap's position for further reads,
      it perfectly suits our needs.
      
      This removes 75% of lseek calls when dumping basic container.
