With the idea to have fanotify(7) return pidfds within a `struct fanotify_event_metadata`, pidfd_create()'s scope is to increased so that it can be called from other subsystems within the Linux kernel. The current `static` qualifier from its definition is to be removed and a new function declaration for pidfd_create() is to be added to the linux/pid.h header file.
