That's true. But if you are writing a profiler, the current process
is the process of interest in the interrupt context.

On a timer interrupt, I tried to stop the current process by changing
it's run state to TASK_STOPPED via set_current_state(TASK_STOPPED).
However, this results in a system hang.
I can't find a way to stop the current process during an interrupt
context. Does such code exist in the kernel? If not, how does one go
about implementing it from within a kernel module.
In interrupt context there's no "current process" by definition.
