@cofyc As this PR also needs API review, and unfortunately tomorrow is the code freeze for 1.19. Per the original plan (targeting 1.20) in KEP, would you mind holding the review until 1.20?

This also needs api reviews.

@kubernetes/api-reviewers Can any API expert take a review? Thanks.

I'm wondering this would break when loop the failedNodesMap in "genernicSchduler.findNodesThatPassExtenders", since we loop on a nil

kubernetes/pkg/scheduler/core/generic_scheduler.go

Line 360 in aa2e6d0

for failedNodeName, failedMsg := range failedMap {

We know that this API doesn't respect openAPI and there is an open issue to fix this in a v2: #88634

This API is used to format messages between scheduler and an external extender.

As it stands today, api-change lgtm.
