I was just looking at lctl get_param mdt.*.job_stats to see what it showed, now that test-framework.sh enables it by default. It appears that the "ll_sa_<pid>" threads are showing up as a separate job for every "ls" being run, instead of only "ls.<uid>" as I would expect.

- job_id:          ll_sa_14097_0
  snapshot_time:   1346211655
  getattr:         { samples:           5, unit:  reqs }

Is it possible to do something like is done for IO, to store the jobid into the inode for the statahead, or pass the JobID on to the statahead thread, so that it doesn't send "ll_sa_*" as the process name?
