But tasklets get called immediately after the hard irq (the irq handler actually calls the tasklet as the last thing). So I don't think it makes much difference, especially if you are using power-save mode where by definition no other IRQs are going to be interrupting the tasklet. There's always tasklet_hi_schedule. The benefit is it makes irq processing much simpler. -- Bob Copeland %% www.bobcopeland.com _______________________________________________ ath5k-devel mailing list ath5k-devel@lists.ath5k.org https://lists.ath5k.org/mailman/listinfo/ath5k-devel
