Re: [PATCH 2/2] leds: trigger: netdev: refactor netdev_event_requires_handling()

Tomorrow i will look at the socket system calls and see how you get a
processes network namespace.

current->nsproxy->net_ns gives the current processes network
namespace.

current is one of those historical odd things, like
jiffies. Originally it was a global variable, when the kernel
supported a single CPU, and hence only a single processes was ever
running. But with the change to SMP it became a #define for a function
call.
