In normal operation, kretprobe makes a target function return to trampoline code. A kprobe (called trampoline_probe) has been inserted in the trampoline code. When the kernel hits this kprobe, it calls kretprobe's handler and it returns to the original return address. Kretprobe-booster removes the trampoline_probe. It allows the trampoline code to call kretprobe's handler directly instead of invoking kprobe. The trampoline code returns to the original return address.
