While perfroming root cause analyses of fence callback list corruptions, a couple of other potential though less likely root causes have been identified in addition to barrier tasks list deletion results ignored. This series tries to fix those potential issues, also in longterm stable releases starting from v5.10. The third patch, while not fixing any real bug, is believed to make the code more predictable and easy to understand, then more easy to debug should other barrier related issue still exist.
