Sorry, libuLinux_hal.so is a customized library which is not available on a=
ny
distro/package/tarabll.  So, instead, I tried to probe the libc.so.6 as bel=
ow
but unfortunately got the same result.

#!/usr/bin/env stap

probe process("/lib/libc.so.6").function("fork")
{
        printf("fork called\n")
}
