kallsyms_expand

函数名称：Expand a compressed symbol data into the resulting uncompressed string,* if uncompressed string is too long (>= maxlen), it will be truncated,* given the offset to where the symbol is in the compressed stream.

函数原型：static unsigned int kallsyms_expand_symbol(unsigned int off, char *result, size_t maxlen)

返回类型：unsigned int

参数：

类型	参数	名称
unsigned int	off
char *	result
size_t	maxlen

skipped_first等于0

data等于kallsyms_names[off]

len等于data

data自加

off加等于len加1

当len 循环

tptr等于kallsyms_token_table[kallsyms_token_index[ * data]]

data自加

len自减

当tptr 循环

如果skipped_first则

如果maxlen小于等于1则转到:tail

result等于tptr

result自加

maxlen自减

否则skipped_first等于1

tptr自加

tail :

如果maxlen则result等于'\0'

101

返回:off
