This can still happen, no? Two tasklets can run in parallel on different processors, as long as they are different tasklets. In practice, this won't happen much because tasklets run on the cpu that scheduled them, and irq affinity is such (at least on my hardware) that it's almost always the same CPU. But I think to make the above true it needs to stop the queues etc when doing calibration. Also we are missing tasklet_kill()? -- Bob Copeland %% www.bobcopeland.com _______________________________________________ ath5k-devel mailing list ath5k-devel@lists.ath5k.org https://lists.ath5k.org/mailman/listinfo/ath5k-devel
