0) I have not yet tried this script, but I did have a look at it (to see what's needed to run it).
1) All debugfs files it polls come from kernel/rcutree_trace.c. That file is written as a module (and will only be built if CONFIG_TREE_RCU_TRACE isn't "n"). But in init/Kconfig, the TREE_RCU_TRACE config entry is set to "def_bool".
2) So shouldn't either the config entry be set to "tristate" or the module support removed from kernel/rcutree_trace.c?
