函数名称：bitmap_list_string

函数原型：static __attribute__((__noinline__)) char *bitmap_list_string(char *buf, char *end, unsigned long *bitmap, struct printf_spec spec, const char *fmt)

返回类型：char

参数：

类型参数名称
char *buf
char *end
unsigned long *bitmap
struct printf_specspec
const char *fmt
1201  nr_bits等于max_t - return maximum of two values, using the specified type*@type: data type to use*@x: first value*@y: second value(int, width of output field , 0)
1204  bool first = true
1206  如果check_pointer( & buf, end, bitmap, spec)则返回:buf
1209  rbot等于cur等于find_first_bit(bitmap, nr_bits)
1210  当cur小于nr_bits循环
1211  rtop等于cur
1212  cur等于d_next_bit - find the next set bit in a memory region*@addr: The address to base the search on*@offset: The bitnumber to start searching at*@size: The bitmap size in bits* Returns the bit number for the next set bit* If no bits are set, returns @size.
1213  如果cur小于nr_bits且cur小于等于rtop加1则继续下一循环
1216  如果非first则
1217  如果buf小于end则buf等于','
1219  buf自加
1221  first = false
1223  buf等于number(buf, end, rbot, default_dec_spec)
1224  如果rbot小于rtop则
1225  如果buf小于end则buf等于'-'
1227  buf自加
1229  buf等于number(buf, end, rtop, default_dec_spec)
1232  rbot等于cur
1234  返回:buf
