Eric W. Biederman 161550d74c pid: sys_wait... fixes ... This modifies do_wait and eligible child to take a pair of enum pid_type and struct pid *pid to precisely specify what set of processes are eligible to be waited for, instead of the raw pid_t value from sys_wait4. This fixes a bug in sys_waitid where you could not wait for children in just process group 1. This fixes a pid namespace crossing case in eligible_child. Allowing us to wait for a processes in our current process group even if our current process group == 0. This allows the no child with this pid case to be optimized. This allows us to optimize the pid membership test in eligible child to be optimized. This even closes a theoretical pid wraparound race where in a threaded parent if two threads are waiting for the same child and one thread picks up the child and the pid numbers wrap around and generate another child with that same pid before the other thread is scheduled (teribly insanely unlikely) we could end up waiting on the second child with the same pid# and not discover that the specific child we were waiting for has exited.
