    Description

      Lustre's proc seems to have had a number of regressions. LMT's ltop is no longer able to find many of the values it used to display.

      In particular, brw_stats from obdfilter is gone, and does not appear to have been replaced after the OSD work. At minimum, that was used by ltop to report the number of bulk rpcs handled.

      The MDS display is also missing a number of values.

      We don't necessarily need to put them back exactly how they were before, but we need to export them in some way that will make them usable for folks.

      It would be best to decide on interfaces before 2.4.0 is locked in.
