Greetings All, I am curious as it after reading the network code for a while it seems that to me at least the rtnl mutex lock is a bottleneck. Is there any reason that we are still using a global mutex for all routing changes in the networking stack for the Linux kernel or does it actually scale only, seems to me that it is causing nothing but problems with deadlocks related to it or issues with locking timeouts on separate netdev routing tables for two different networks. Is this just me or does this lock actually cause serious issues or can do so. Regards, Nick
