Hello everyone

I have meeted a problem with linux kernel 2.6.X.X that my user app wants to
get thread kernel stack frame ponter(FP)
from user space by system call or /proc system or any other ways except
driver. I do not want to write a driver,) to steal
FP from kernel. I have tried to use ptrace syscall to get FP with command
PTRACE_GETREGS, but It returns only user 
stack FP rather than kernel stack fp.

would anyone please to give me a hint to solve the problem.


thanks a lot.

regards

Bob Wang
