The worst case would most likely be in a dm multipath configuration where you could get a burst of N number events (N being equal to the number of luns times the number of paths that are having an issue).

Yes, the ones that are part of this patch are unexpected events or recovery of the unexpected event. > Worst case you handle extra kmallocs with a library function. > It's not like you are using GFP_ATOMIC. I was using GFP_ATOMIC as I did not want __GFP_IO as in some testing there was a case where heavy file system IO was going on and an injected error event caused the swap device into a temporary queued condition while an event was trying to be sent. I may need to go back and investigate this case on recent kernels as it has been a while since I did the test case. -andmike -- Michael Anderson [EMAIL PROTECTED] - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
