Re: [RFC PATCH 2/6] Split out tasklets from softirq.c

2007/6/22, Steven Rostedt <[email protected]>:

+static inline void tasklet_unlock_wait(struct tasklet_struct *t)
+{
+       while (test_bit(TASKLET_STATE_RUN, &(t)->state)) { barrier(); }
+}

BTW, can we use cpu_relax() instead of barrier() in this busy-wait loop?
