__clone() is a function with a defined interface. How it is implemented
is not given in the name. Why should __clone() have to be implemented
using the SYS_clone system call? If I understood the thread so far
correctly, the final kernel will not even have SYS_clone.
Compare with open(), which is often implemented in terms of SYS_openat
instead of SYS_open. Or qsort(), which, despite the name, is rarely
implemented as a quicksort.
So no, there will be no confusion of system calls because a function is
not implemented in terms of the system call of the same name, as long as
the function fulfills the defined interface.
Ciao,
Markus
