      [BLUETOOTH]: put_device before device_del fix · 38b7da09
      Dave Young authored
      Because of workqueue delay, the put_device could be called before
      device_del, so move it to del_conn.

      [TCP]: use non-delayed ACK for congestion control RTT · 2072c228
      Gavin McCullagh authored
      When a delayed ACK representing two packets arrives, there are two RTT
      samples available, one for each packet.  The first (in order of seq
      number) will be artificially long due to the delay waiting for the
      second packet, the second will trigger the ACK and so will not itself
      be delayed.
      
      According to rfc1323, the SRTT used for RTO calculation should use the
      first rtt, so receivers echo the timestamp from the first packet in
      the delayed ack.  For congestion control however, it seems measuring
      delayed ack delay is not desirable as it varies independently of
      congestion.
      
      The patch below causes seq_rtt and last_ackt to be updated with any
      available later packet rtts which should have less (and hopefully
      zero) delack delay.  The rtt value then gets passed to
      ca_ops->pkts_acked().
      
      Where TCP_CONG_RTT_STAMP was set, effort was made to supress RTTs from
      within a TSO chunk (!fully_acked), using only the final ACK (which
      includes any TSO delay) to generate RTTs.  This patch removes these
      checks so RTTs are passed for each ACK to ca_ops->pkts_acked().
      
      For non-delay based congestion control (cubic, h-tcp), rtt is
      sometimes used for rtt-scaling.  In shortening the RTT, this may make
      them a little less aggressive.  Delay-based schemes (eg vegas, veno,
      illinois) should get a cleaner, more accurate congestion signal,
      particularly for small cwnds.  The congestion control module can
      potentially also filter out bad RTTs due to the delayed ack alarm by
      looking at the associated cnt which (where delayed acking is in use)
      should probably be 1 if the alarm went off or greater if the ACK was
      triggered by a packet.

      [SERIAL]: Fix section mismatches in Sun serial console drivers. · fb445ee5
      David S. Miller authored
      We're exporting an __init function, oops :-)
      
      The core issue here is that add_preferred_console() is marked
      as __init, this makes it impossible to invoke this thing from
      a driver probe routine which is what the Sparc serial drivers
      need to do.
      
      There is no harm in dropping the __init marker.  This code will
      actually work properly when invoked from a modular driver,
      except that init will probably not pick up the console change
      without some other support code.
      
      Then we can drop the __init from sunserial_console_match()
      and we're no longer exporting an __init function to modules.

      cmd64x: fix hwif->chipset setup · deffca11
      Bartlomiej Zolnierkiewicz authored
      commit 528a572d ("ide: add ->chipset field
      to ide_pci_device_t") broke hwif->chipset setup (it is now set to ide_cmd646
      for CMD648 instead of CMD646).  It seems that the breakage happend while
      I was moving patches around (cmd64x_chipsets[] entries for CMD646 and CMD648
      are identical except for 'name' field).  Fix it and bump driver version.
