As described in LDD3, chapter 2, page 21, the current pointer always points to the process currently running on the relevant CPU. When you're running in interrupt context there is _no_ currently running process thus there is no process context which means you cannot access the current pointer. Someone please correct me if I'm wrong. Cheers, Tobias -- Kernelnewbies: Help each other learn about the Linux kernel.
