返回类型：int

参数：

类型参数名称
char *str
58  schedstr[]等于"schedule"
59  sleepstr[]等于"sleep"
60  kvmstr[]等于"kvm"
63  如果非字符串指定长度比较则
74  打印警告信息("kernel sleep profiling requires CONFIG_SCHEDSTATS\n")
76  否则如果非字符串指定长度比较则
77  prof_on等于SCHED_PROFILING
78  如果str[strlen - Find the length of a string*@s: The string to be sized]恒等于','则str加等于strlen - Find the length of a string*@s: The string to be sized加1
80  如果get_option - Parse integer from an option string*@str: option string*@pint: (output) integer value parsed from @str* Read an int from an option string; if available accept a subsequent* comma as well则prof_shift等于par
82  打印信息("kernel schedule profiling enabled (shift: %ld)\n", prof_shift)
84  否则如果非字符串指定长度比较则
85  prof_on等于KVM_PROFILING
86  如果str[strlen - Find the length of a string*@s: The string to be sized]恒等于','则str加等于strlen - Find the length of a string*@s: The string to be sized加1
