It is, in some senses, like processor architectures that have one or more special purpose registers reserved for user use. They are saved and restored on context switches but don't have any role in the processor architecture. Instead, they hold things like a pointer to the current thread's user space context, such as thread local storage. Something that just holds a bit of information in the kernel for use outside the kernel might be just the solution to the container ID issue.<br> <p> Thanks for the pointer to this!<br> </div> Fri, 15 Dec 2017 22:03:40 +0000
