I'm thinking > 5.21-rc1 with a cc:stable? Yeah, 5.20-rc1 sounds fast. Let's wait for reviews first and see how much confidence we get on that change. I can't help but feel, reading logs and comments (commit 1a501907bbea8e6ebb0b16cf6db9e9cbf1d2c813), that my fix is how the code was intended to work from the start. 5.21 does sound a biiiit on the long side for fixing such extreme misbehavior, IMO, once it's proven to affect production workloads in the wild. I was hoping -rc2 or so...
