By default, debugfs is not mounted world-readable, so no matter what the
permissions are on the files, "normal" users can't access them.
See commit 82aceae4f0d4 ("debugfs: more tightly restrict default mount mode")
that was in 3.7 for the last "tightening up" of the permissions on the
filesystems.
Does your distro override those values?
