What's your validation process for new Kernel releases ?
Same as any software with staged rollout, only more nuanced for different workloads in non-edge environments where machines are dedicated for specific workloads (Kafka, Clickhouse, etc.). This bump was easier than 4.14 -> 4.19, since we started testing at 5.4-rc2.
But do you run any specific tests ? Or staged rollout + look for any regression during the rollout ?
We do have KASAN in one of the stages and there are general performance tests in simulations prior to any customers (employees are first customers), but the sad reality is that real users are still better at finding bugs at scale.
