[Petr Vorel]

Hi,

Cc Jan, which replied to my question in private mail.

Kind regards,
Petr

>                  from fanotify04.c:25:
> ../../../../include/lapi/fanotify.h:198:2: error: unknown type name ‘__s32’
>   198 |  __s32 error;
>       |  ^~~~~
> ../../../../include/lapi/fanotify.h:199:2: error: unknown type name ‘__u32’
>   199 |  __u32 error_count;
>       |  ^~~~~

> NOTE: Historically we tried to minimize number of linux includes,

> time and LTP also dropped support for archaic kernels over time.
> Therefore we can keep original kernel types here.
