* int bpf_strtol(const char *buf, size_t buf_len, u64 flags, long *res)
* Description
* Convert the initial part of the string from buffer *buf* of
* size *buf_len* to a long integer according to the given base
* and save the result in *res*.
*
* The string may begin with an arbitrary amount of white space
* (as determined by isspace(3)) followed by a single optional '-'
* sign.
*
* Five least significant bits of *flags* encode base, other bits
* are currently unused.
*
* Base must be either 8, 10, 16 or 0 to detect it automatically
* similar to user space strtol(3).
* Return
* Number of characters consumed on success. Must be positive but
* no more than buf_len.
*
* **-EINVAL** if no valid digits were found or unsupported base
* was provided.
*
* **-ERANGE** if resulting value was out of range.
