[PATCH] fork: total_forks not counted under tasklist_lock
Bring the total_forks under tasklist_lock. When most of the fork code
icluding nr_threads is moved to copy_process() from do_fork() code in 2.6,
this is left out.
Althought accuracy of total_forks is not important, it would be nice to add
this. It does not involve additional cost, and the code will be cleaner if
it is grouped with nr_threads. The difference is, total_forks will
increase on fork, but nr_threads will increase on fork and decrease on the
exit.
I also moved extern decleration to sched.h from proc_misc.c.
