Hey folks --While digging through the atl1 source, I was troubled by the code using irq_sem. I did some digging and found the same code in e1000 and ixgb. I'm not entirely sure what it was originally intended to do, but it doesn't seem to be doing anything useful now, except possibly locking interrupts off if NAPI is flipped on and off enough times to cause an integer overflow. The following patches completely remove irq_sem from each of the drivers. This has been tested successfully on atl1 and e1000. If someone would like to send me ixgb hardware I'd be glad to test that, otherwise you'll have to test it yourself. :) -- Chris
I'm not yet seeing patches 1/3 appear, but I'll certainly take a look at them and have them tested in our labs once they appear for e1000 and ixgb.
