Interesting. It was discussed on stable@ in March between Eric and Paul about the pertinence of merging it into 2.6.32 and 2.6.34 (both CCed). The thread was '[PATCH] net: reduce net_rx_action() latency to 2 HZ'. It is supposed to fix a but introduced in 2.6.29 by commit 24f8b2385 (net: increase receive packet quantum). I didn't notice that it was not in more recent versions. Eric, do you suggest that I revert this patch or that I also include the mainline fix above to fix the regression ? If the latter, should Paul and Greg also take the two patches ?
