Could this be please backported to 5.15 and earlier? It is already part of the 6.X kernels. I asked about this by the end of January and I'm kindly asking again ;)
I thought this was only an issues when using the out-of-tree RT patches with these kernels, right? Or is it relevant for 5.15.y from kernel.org without anything else?
The out-of-tree RT patches make extensive use of the code. Since it is upstream code, I assumed it should go via the official stable trees. Without RT, the code is limited the rt_mutex_lock() used by I2C and the RCU booster-mutex. Since this might not be enough to trigger the problem, let me route this via rt-stable trees.
