H A Dreliable-stacktrace.rst163 to intercept when that function returns with a return trampoline, e.g.
165 * An ftrace trampoline may modify the return address so that function graph
168 * A kprobes (or optprobes) trampoline may modify the return address so that
174 is altered by the trampoline, the unwinder may report the original return
175 address in place of the trampoline and report this as reliable. Otherwise, an
180 trampoline or return trampoline. For example, considering the x86_64
181 'return_to_handler' return trampoline:
213 trampoline moves this into rdi before jumping to it.
