Hi Ingo,
Here are two patches for fixing bugs in kprobes, related to
optprobe and enable/disable kprobe knob.
These are reported and fixed by Wang Nan.
https://lkml.org/lkml/2015/1/5/270
https://lkml.org/lkml/2015/1/19/680
Thank you,

Wang Nan (2):
[BUGFIX]kprobes: set kprobes_all_disarmed earlier to enable re-optimization.
[BUGFIX]kprobes: makes kprobes/enabled works correctly for optimized kprobes.

In original code, the probed instruction doesn't get optimized after
echo 0 > /sys/kernel/debug/kprobes/enabled
echo 1 > /sys/kernel/debug/kprobes/enabled
This is because original code checks kprobes_all_disarmed in
optimize_kprobe(), but this flag is turned off after calling that
function. Therefore, optimize_kprobe() will see
kprobes_all_disarmed == true and doesn't do the optimization.
This patch simply turns off kprobes_all_disarmed earlier to enable
optimization.

You sent the patches, so this should have been "Signed-off-by:".
Documentation/SubmittingPatches section 12 has the details.
I have made that change to my copy of these two patches.

debugfs/kprobes/enabled doesn't work correctly on optimized kprobes.
Masami Hiramatsu has a test report on x86_64 platform:
https://lkml.org/lkml/2015/1/19/274
This patch forces it to unoptimize kprobe if kprobes_all_disarmed
is set. It also checks the flag in unregistering path for skipping
unneeded disarming process when kprobes globally disarmed.

Hi Ingo,
Is there any problem on these patches? I'm unable to find them in upstream kernel
and -tip repository.
Thank you.
