That sounds like a problem for architectures that still discard the __exit section at link time to reduce the size of the linked kernel image - though, obviously, if using the plugin results in a smaller kernel image _with_ the exit sections, then there's a net benefit size-wise. -- RMK's Patch system: http://www.armlinux.org.uk/developer/patches/ FTTC broadband for 0.8mile line: currently at 9.6Mbps down 400kbps up according to speedtest.net.
