Q about do_fork()

["petur thors" <peturth@hi.is>]

Hi
I was wondering. If you are on an SMP machine and two diffirent processes do
a fork() or a clone() system call at the same time, can the corresponding
kernel control paths enter the do_fork fuction in kernel/fork.c at the same
time or is one locked out while the other does his thing. I would be very
happy if someone could give me a hint.
Many, many thanks.
