Hi,
Is there a way to find, in the kernel src tree, which routine/function is
calling another function OR kernel function invocation stack order?
This would be helpful for me to know the various steps/functionalities
involved during executing something in kernel space.

At runtime you can use dumpstack() [1].
Otherwise, just for reading the code I suggest cscope [2].
thanks,
Daniel.

Thank you Daniel for the links.
Am using kernel-2.6.18-194.centosplus.el5 and dumpstack.c (under
lib/dumpstack.c) implentation said simply "This architecture does not
support dump_stack".
Thanks, Sri.
