Hi @apullo777. Thanks for your PR.

I'm waiting for a etcd-io member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Please rebase

[MadhavJivrajani]

Not sure if the rebase was successful, I still see changes from #20362 in here

Also feel free to remove from draft state now

Sorry. Just rebased. I will also open a separate PR to make cancelReason public.

[serathius]

It might take some time to get the cancel Reason PR merged. Maybe we could just remove dependence on that and merge the changes to cache?

[apullo777]

Ok. Maybe to temporarily remove the test for WithPreKV so that integration can pass without exposing cancelReason?

[serathius]

CancelReason change was merged. We can move forward. Please rebase.

/test pull-etcd-integration-4-cpu-arm64

Looks like #20378 (comment) is breaking the verify test

@fuweid fyi ^

@apullo777 let's add in a separate commit to this PR to fix that doc comment.

@apullo777 please rebase it when you have time. thanks!
