If you're referring to https://lkml.org/lkml/2020/1/11/634 as the build failure report, this is precisely my series fixes. I sent this series to address the build break reported by Nathan. The original patches were picked up from the "Fixes" tag automatically which broke the build due to missing "event" parameter. This series fixes those build issues and for sure builds fine for the affected versions. Trust me ;-) Cheers Suzuki > greg k-h > ^ permalink raw reply [flat|nested] 18+ messages in thread
