This patch implements task_in_pid_ns and uses it to limit cap_set_all
and sys_kill(-1,) to only those tasks in the current pid namespace.
Some watchdog drivers initialize global spinlocks in module's init function
which is tolerable, but some do it in PCI probe function. So, switch to
static initialization to fix theoretical bugs and, more importantly, stop
giving people bad examples.

we think of any better name for this? It seems a bit funky that:

Well the unix way is to implement it simple and stupid and then to
optimize, where needed. We don't currently have a per pid
