The osnoise/per_cpu/CPU$/timerlat_fd is create for each possible CPU, but it might create confusion if the CPU is not online. Create the file only for online CPUs, also follow hotplug by creating and deleting as CPUs come and go. Fixes: e88ed227f639 ("tracing/timerlat: Add user-space interface")Is this a fix that needs to go in now and Cc'd to stable? Or is this something that can wait till the next merge window?
