函数原型：static int __init parse_crashkernel_simple(char *cmdline, unsigned long long *crash_size, unsigned long long *crash_base)

返回类型：int

参数：

类型参数名称
char *cmdline
unsigned long long *crash_size
unsigned long long *crash_base
126  cur等于cmdline
128  crash_size等于memparse - parse a string with mem suffixes into a number*@ptr: Where parse begins*@retptr: (output) Optional pointer to next char after parse completes* Parses a string into a number. The number stored at @ptr is
129  如果cmdline恒等于cur则
130  打印警告信息("crashkernel: memory value expected\n")
131  返回:负EINVAL
134  如果cur恒等于'@'则crash_base等于memparse - parse a string with mem suffixes into a number*@ptr: Where parse begins*@retptr: (output) Optional pointer to next char after parse completes* Parses a string into a number. The number stored at @ptr is
