[LU-5862] Jobstats tracking in changelogs doesn't support jobid_var=disable

• Type: Bug
• Resolution: Fixed
• Priority: Critical
• Fix Version/s: Lustre 2.7.0
• Affects Version/s: Lustre 2.7.0
• Labels: HB patch
• Environment: Seen on master as of b6a3222

Description

The work that has been done for LU-1996 seems to have introduced an odd bug in changelogs when jobid_var=disable. I don't know enough about this area to speculate on severity, but it seems pretty serious to me. The upshot is that changelogs don't make sense with the default jobid_var setting.

Please see the attached reproducer script for details.

Hi. I haven't started working on a patch. It would probably be faster for you to create one, since you're familiar with the code already. While you're in there, would you also please take a look at LU-5859 to see if it's related? It may not be – I haven't done a bisect to figure out when that one was introduced. It seems plausible that they could be related, though.

Looks like you're right, this regression was introduced by LU-1996. Are you already on it or shall I work on a patch?
