Rejection is temporary ;).  It flaked out on the 4.9.23 -> rc.6 update job, but a later replacement run of that job passed, and now the release is accepted and it's in candidate-4.10 [1].

Verification testing is complete.   @weliang will sync with engineering to confirm results
Comment 9 Weibin Liang 2022-03-01 15:01:27 UTC 
Tested and verified in 4.10.0-rc.6-x86_64


During cluster upgrading, SVC LB traffic disruptions happened three times when three worker nodes got rebooting. Without PR upgrading testing, each disruption time is about 7.1 seconds, with PR upgrading testing, two disruption time is about 1.1 seconds, one disruption time is about 3.0 seconds, I can see some improvements with fix PR in my testing cluster
