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,
Josef

HI Josef, thanks for your reply.
Thankfully it's not the root FS.
There are 3 btrfs filesystems on that system.
