      pktgen: Fix multiqueue handling · 896a7cf8
      Eric Dumazet authored
      It is not currently possible to instruct pktgen to use one selected tx queue.
      
      When Robert added multiqueue support in commit 45b270f8
      
      , he added
      an interval (queue_map_min, queue_map_max), and his code doesnt take
      into account the case of min = max, to select one tx queue exactly.
      
      I suspect a high performance setup on a eight txqueue device wants
      to use exactly eight cpus, and assign one tx queue to each sender.
      
      This patchs makes pktgen select the right tx queue, not the first one.
      
      Also updates Documentation to reflect Robert changes.

      ext4: Use tracepoints for mb_history trace file · 296c355c
      Theodore Ts'o authored
      
      
      The /proc/fs/ext4/<dev>/mb_history was maintained manually, and had a
      number of problems: it required a largish amount of memory to be
      allocated for each ext4 filesystem, and the s_mb_history_lock
      introduced a CPU contention problem.  
      
      By ripping out the mb_history code and replacing it with ftrace
      tracepoints, and we get more functionality: timestamps, event
      filtering, the ability to correlate mballoc history with other ext4
      tracepoints, etc.
