As function sscanf is banned, to get value from parameter buffer,strto*
is recommended. To reduce the inspection code when using strto*, it's
better to use a string convert API.
Usage:
For virtio-blk, it has parameters:
range=<start lba>/<subfile size>
sscanf:
if (sscanf(cp, "range=%ld/%ld", &sub_file_start_lba,
&sub_file_size) == 2)
sub_file_assign = 1;
string API:
if (strsep(&cp, "=") &&
!dm_strtol(cp, &cp, 10, &sub_file_start_lba) &&
*cp == '/' &&
!dm_strtol(cp + 1, &cp, 10, &sub_file_size))
sub_file_assign = 1;
