返回类型：void

参数：无

42  These can be used to print at the various log levels.* All of these will print unconditionally, although note that pr_debug()* and other debug macros are compiled out unless either DEBUG is defined* or CONFIG_DYNAMIC_DEBUG is set.(" Depth Size Location (%d entries)\n ----- ---- --------\n", stack_trace_nr_entries)
46  以i小于stack_trace_nr_entries循环
47  如果i加1恒等于stack_trace_nr_entries则size等于stack_trace_index[i]
49  否则size等于stack_trace_index[i]减stack_trace_index[i + 1]

名称描述
check_stackThe stack tracer looks for a maximum stack at each call from a function. It* registers a callback from ftrace, and in that callback it examines the stack* size. It determines the stack size from the variable passed in, which is the
