函数名称：TRACE_STACK

函数原型：static enum print_line_t trace_stack_print(struct trace_iterator *iter, int flags, struct trace_event *event)

返回类型：enum print_line_t

参数：

类型参数名称
struct trace_iterator *iter
intflags
struct trace_event *event
1066  s等于 The below is zeroed out in pipe_read
1070  The trace_assign_type is a verifier that the entry type is* the same as the type being assigned. To add new types simply* add a line with the following format:* IF_ASSIGN(var, ent, type, id);* Where "type" is the trace type that includes the trace_entry(field, ent)
1071  end等于ent加ent_size
1073  trace_seq_puts(s, "<stack trace>\n")
1075  以p且p小于end且p不等于ULONG_MAX循环
1077  如果跟踪泛滥则退出
1080  trace_seq_puts(s, " => ")
1081  seq_print_ip_sym(s, * p, flags)
1082  trace_seq_putc(s, '\n')
1085  返回:Several functions return TRACE_TYPE_PARTIAL_LINE if the trace_seq* overflowed, and TRACE_TYPE_HANDLED otherwise. This helper function* simplifies those functions and keeps them in sync.
