Met Problem on Enable SystemTap on Android

I think you need debugfs to be mounted so that relayfs does not try to go to /mnt/relay

Should be "mount -t debugfs none /sys/kernel/debug"

Then you get:
 /sys/kernel/debug /sys/kernel/debug debugfs rw,relatime 0 0

Systemtap create files in /sys/kernel/debug/systemtap
