I have never tried this, but I don't see why a system call cannot be done
within the kernel. I don't know if a "system()" function is available
within the kernel (check the documentation) but surely you could at least
write an assembly-language routine to set up the arguments and issue an
"int 0x80" instruction.

Why do you want to schedule a user process from the kernel?
