Hi , Is there a way by which we can trace the flow of execution of a process , when it is executing the kernel code path ? Any tool which does this would help understand which all functions / code path is taken in the kernel when a particular program executes . strace provides just the system call invocation , but I would like to know what happens within the kernel when the system call executes .
