Trevor King on 2020-10-09 04:19:58 UTC --- Looks like we need an upstream client-go fix backported. I'll try to figure out what our process is for that... --- Additional comment from W. Trevor King on 2020-10-09 05:51:19 UTC --- I've filed an upstream PR requesting a backport to 1.17. --- Additional comment from Scott Dodson on 2020-10-09 13:51:13 UTC --- This is 4.5 specific but the bot will revert my changes if i set target release to 4.5 directly, so setting it 4.7 now to get off the blocker list. --- Additional comment from W. Trevor King on 2020-10-09 18:51:56 UTC --- 4.6+ use 1.19 clients which have this patched, so setting this modified to unblock a new-in-4.5 patch. --- Additional comment from W.
