[Bug kprobes/9740] syscall.* probe causes kernel panic(double fault) on rawhide kernel/i686


------- Additional Comments From mhiramat at redhat dot com  2009-01-13 23:07 -------
Here, I checked unloading time on 2.6.28-mm1 on 2CPU machine.

$ time staprun -d syscall2.ko 

real	0m0.340s
user	0m0.000s
sys	0m0.014s

As you can see, real took over 340ms because synchronize_sched() waits scheduler
synchronization.
