返回类型：void

参数：

类型参数名称
intis_user
360  DECLARE_BITMAP(查找文件中的块号, 2048)
361  mode等于如果is_user则"_user"否则""
363  以i小于ARRAY_SIZE - get the number of elements in array @arr*@arr: array to be sized(parselist_tests)循环
366  如果is_user则
367  orig_fs等于获取当前进程地址空间上限()
368  len等于strlen(in)
370  set_fs(KERNEL_DS)
371  time等于ktime_get()
372  err等于map_parselist_user()*@ubuf: pointer to user buffer containing string.*@ulen: buffer size in bytes. If string is smaller than this* then it must be terminated with a \0.*@maskp: pointer to bitmap array that will contain result.
374  time等于ktime_get()减time
375  set_fs(orig_fs)
376  否则
377  time等于ktime_get()
378  err等于map_parselist - convert list format ASCII string to bitmap*@buf: read user string from this buffer; must be terminated* with a \0 or \n
379  time等于ktime_get()减time
382  如果err不等于errno则
383  打印错误信息("parselist%s: %d: input is %s, errno is %d, expected %d\n", mode, i, in, err, errno)
385  继续下一循环
388  如果非err且expected且非DOC: bitmap introduction* bitmaps provide an array of bits, implemented using an an* array of unsigned longs则
390  打印错误信息("parselist%s: %d: input is %s, result is 0x%lx, expected 0x%lx\n", mode, i, in, 查找文件中的块号, * expected)
393  继续下一循环
396  如果flags按位与PARSE_TIME则打印错误信息("parselist%s: %d: input is '%s' OK, Time: %llu\n", mode, i, in, time)
