Back in the 2.4.x days one could periodically run "rmmod -as" to unload those kernel modules that were not in use. How does get the same functionality with contemporary kernels? I have a machine that is very rarely rebooted but somewhat low on system memory. I find the the number of kernel modules in use goes up over time. A given module is demand-loaded as needed but remains indefinitely after the need for it is gone. So... how can I auto-unload 2.6.x kernel modules? Thanks.
