详细了解printk后，发现还有更简便的方法。
|

|
||
%p：打印裸指针(raw pointer)
|
||
|
||
%pF可打印函数指针的函数名和偏移地址
|
||
|
||
%pf只打印函数指针的函数名，不打印偏移地址。
|
||
|
||
如
|
||
printk("%pf",func[0]->action); 结果：
|
||
my_Set
|
||
|
||
%pM打印冒号分隔的MAC地址
|
||
|
||
%pm打印MAC地址的16进制无分隔
|
||
|
||
如
|
||
printk("%pM %pm\n", mac, mac) willprint:
|
||
|
||
2c:00:1d:00:1b:00 2c001d001b00
|
||
|
||
%I4打印无前导0的IPv4地址，%i4打印冒号分隔的IPv4地址
|
||
%I6打印无前导0的IPv6地址，%i6打印冒号分隔的IPv6地址
|
||
如
|
||
printk("%pI4 %pi4\n", ip, ip) will print:
|
||
127.0.0.1 127:0:0:1
