it will ouput the current stack, or disable it.

+TRACE-CMD-STACK(1)
+==================
+
+NAME
+----
+trace-cmd-stack - read, enable or disable Ftrace Linux kernel stack tracing.
+
+SYNOPSIS
+--------
+*trace-cmd stack*
+
+DESCRIPTION
+-----------
+The trace-cmd(1) stack enables the Ftrace stack tracer within the kernel.
+The stack tracer enables the function tracer and at each function call
+within the kernel, the stack is checked. When a new maximum usage stack
+is discovered, it is recorded.
+
+When no option is used, the current stack is displayed.
+
+To enable the stack tracer, use the option *--start*, and to disable
+the stack tracer, use the option *--stop*. The output will be the maximum
+stack found since the start was enabled.
+
+Use *--reset* to reset the stack counter to zero.
