Well, it's a bit unlikely that they understand network namespaces. > I was hoping I could get a brief review on the adding of network > namespace support here. Most network namespace work is done on net...@vger.kernel.org, but they probably won't understand all the SCSI bits, but perhaps they don't need to; it's basically the netlink and the filters, right? The other list that would take a more generic view is the containers one contain...@lists.linux-foundation.org because that's where most namespace stuff ends up.
