We should document this somewhere. Documentation/ABI/ is the formal
place for sysfs files, but nobody will think to look there for VM
things, so perhaps place a pointer to the Documentation/ABI/ files
within Documentation/vm somewhere, only there isn't an appropriate
Documentation/vm file ;)
Or just put all these things in debugfs. These are pretty specialized
things and appear to be developer-only files of short-term interest?
