    * obdfs/flushd.c: conditionalized number of C_DEBUG messages.
        * include/linux/obd_class.h: added obd_devicename member to
          struct obd_device (name is either ptr to dentry or uuid).
        * ext2obd/ext2_obd.c: setup() converts dentry into rdev number.
          class/class_obd.c: setup() converts name into obd_device dentry
          class/obdcontrol: setup() passes /dev/obd name into ioctl
          (used to be rdev number and if invalid rdev number was passed
           old ext2_obd.c would crash kernel when trying to read superblock).
        * class/obdcontrol: added "status, procsys, script, insmod, rmmod,
          lsmod, shell and close" commands for obdcontrol. This allows
          easier scripting from within obdcontrol. Introduced ability to
          maintain multiple open obd devices from a single obdcontrol
          session.  Device command toggles device context. Obdcontrol
          maintains multiple open file handles. "script <file>" command is
          useful for "sourcing" scripts without leaving obdcontrol.
          shell <command> allows any shell command to be executed from
          within obdcontrol.
        * class/proc_lustre.c: added support for /proc/lustre/obd/<n>/status.
          These are read-only /proc entries that track /dev/obd<n>
          internal state.
        * obdtrace/* & include/linux/obd_class.h: obd_trace a logical obd
          module useful for tracing and performance debug of the Lustre
          obd protocol stack. obdtrace module creates
          /proc/lustre/obd/<n>/stats file. Reading this /proc file shows
          per OBD performance statistics.  Any write to this /proc file
          resets the counters for this OBD.
        * scripts/obdtrace_demo.scr: Example of obdtrace that
          takes advantage of new obdcontrol functionality.
        * doc/obdtrace_demo.txt: shows obdtrace capabilities.
