Subject[RFC] Race condition?
Is there a race condition in this piece of code from do_fork in
linux/kernel/fork.c? I cannot see what prevents two processes
from calling this at the same time and both successfully fork
even though the user had only one process left.

if (atomic_read(&p->user->processes) >= p->rlim[RLIMIT_NPROC].rlim_cur
&& !capable(CAP_SYS_ADMIN) && !capable(CAP_SYS_RESOURCE))
goto bad_fork_free;
