    Description

      The addition of the start_time and elapsed_time fields in the lprocfs stats header in patch https://review.whamcloud.com/49745 "LU-11407 obdclass: add start time to stats files" may break stats parsing if it has not been updated to understand these fields.

      Add a tunable parameter "enable_stats_header" to allow the header to be enabled/disabled globally.
