This set makes some changes to the new buf_ring API to help it's usability. Most importantly the _add function needs a mask parameter to prevent buffer overflow. I added a _mask helper function to calculate this. Even though its trivial it feels better to not force the user to think about it. Additionally _init is required as otherwise there is no provided way to sync the tail with the kernel. Lastly I add a test that showed up some issues found in 5.19-rc1. Patch 1 is a small man fix Patch 2/3 are the API changes Patch 4 is the test.
