Hi Timo,

For me the mount point changes permission when mounted, and from the hard link 
count I guess you have it unmounted.

tsunami:~# umount /sys/kernel/debug/
tsunami:~# ls -ld /sys/kernel/debug/
drwxr-xr-x 2 root root 0 Jul 30 13:08 /sys/kernel/debug/
tsunami:~# mount -t debugfs none /sys/kernel/debug
tsunami:~# ls -ld /sys/kernel/debug/
drwx------ 16 root root 0 Jul 29 08:52 /sys/kernel/debug/

I'm using a local build of 3.10.2.

Regards,
Steve
