Hi, I'm developing a module for Linux kernel. Some of the processing happens in interrupt context and there are some common variables for which mutual exclusion is to be assured. Is disabling interrupts before using the variables the only option ? If interrupts get disabled very frequently, it affects timed operations (like a timer-function).. Any help is apreciated..
