What's the > expected ratio of directories to non-directories in sysfs? Current sysfs / kobject design _require_ that dentries for the leaves to be present all the times. There is simply no generic way to find attributes of a kobject. As of now it uses dentry->d_fsdata to reach to the attribute. In my system leaves are around 65% of the total.
