Will a workqueue react the same in case of a DDOS situation, where softirq could use all CPU cycles to handle incoming packets and feed the GC list, and GC would never have a chance to scan and free some items ? About chunk processing, I did it on purpose, to not throw away all CPU cache. Goal is to process entries, but not all of them in a row, especially if we find many yet referenced entries (and thus not candidates to freeing) Thanks - 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
