SMP safe code Actual source code when recompiling modules Reviewing things like driver code use of disable_irq by hand Reviewing driver code for situations where it requires a small timing delay and a large one is unacceptable Checking anywhere you use the cpu id that you don't do somthing where it might change under you (eg per cpu variables) - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
