Since this went in I'm seeing:

kernel/kprobes.c:719: warning: �arm_kprobe� defined but not used

from the arch/ia64/configs/zx1_defconfig build on ia64

Looks to be because that config ends up with:

CONFIG_KPROBES=y

together with

# CONFIG_DEBUG_FS is not set

Ah, thank you for reporting!
Hmm, it seems that the place of definitions of enable_kprobe/disable_kprobe
which call arm_kprobe/disarm_kprobe, are incorrect, because those functions
are just API and don't depend on debugfs.
I'll fix that.


Thank you,
