Hi, Please consider the following definitions from include/linux/irq_cpustat.h -------------------------- #ifdef CONFIG_SMP #define __IRQ_STAT(cpu, member) (irq_stat[cpu].member) #else #define __IRQ_STAT(cpu, member) ((void)(cpu), irq_stat[0].member) #endif /* arch independent irq_stat fields */ #define softirq_pending(cpu) __IRQ_STAT((cpu), __softirq_pending) #define local_irq_count(cpu) __IRQ_STAT((cpu), __local_irq_count) ----------------------------- Why __IRQ_STAT is defined differently for UP and SMP ?. Because of this I am not able to use local_irq_count() and such things as Lvalues under UP. (like local_irq_count(cpu) = 0) Regards, Bharata. -- Bharata B Rao, IBM Linux Technology Center, IBM Software Lab, Bangalore.
