Hi folks, we have (at least) two severe regressions in stable releases right now. [SHAs are from linux-5.10.y] 2435dcfd16ac spi: mediatek: fix fifo rx mode Breaks SPI access on all Mediatek devices for small transactions (including all Mediatek based Chromebooks since they use small SPI transactions for EC communication) 60789afc02f5 Bluetooth: Shutdown controller after workqueues are flushed or cancelled Breaks Bluetooth on various devices (Mediatek and possibly others) Discussion: https://lkml.org/lkml/2021/7/28/569 Unfortunately, it appears that all our testing doesn't cover SPI and Bluetooth. I understand that upstream is just as broken until fixes are applied there. Still, it shows that our test coverage is far from where it needs to be, and/or that we may be too aggressive with backporting patches to stable releases. If you have an idea how to improve the situation, please let me know. Thanks, Guenter
