      [IPV4]: Convert do_gettimeofday() to getnstimeofday(). · f25c3d61
      YOSHIFUJI Hideaki 提交于
      What do_gettimeofday() does is to call getnstimeofday() and
      to convert the result from timespec{} to timeval{}.
      After that, these callers convert the result again to msec.
      Use getnstimeofday() and convert the units at once.

      [NET]: Expose netdevice dev_id through sysfs · 9d29672c
      David Woodhouse 提交于
      Expose dev_id to userspace, because it helps to disambiguate between
      interfaces where the MAC address is unique.
      
      This should allow us to simplify the handling of persistent naming for
      S390 network devices in udev -- because it can depend on a simple
      attribute of the device like the other match criteria, rather than
      having a special case for SUBSYSTEMS=="ccwgroup".
