I found it easier to comment about this here, instead of where the code
implemented this, as you describe it well here:

As this is primarily debugging information, why not just always enable
it, and put in debugfs instead of in procfs? That's where new debugging
information should be going. Side benefit, your code should shrink a
bit if you use debugfs instead of procfs :)

Or, if this is really needed by all users, what is wrong with
/sys/fs/f2fs/ instead?

thanks,
