> How much metadata do you have on this fs? I was going to hold everything in bpf hash trees, but I’m worried we’ll hit collisions and then the tracing will be useless. If it’s too big I’ll have to dump everything to userspace and let python take care of keeping everything in memory, so if you have a lot of metadata hopefully you have lots of memory too ;). Thanks,
