Hi Greg,
Ok, I see the problem.
But why kernel 2.2 offers the way to remove all unused modules by
this:"rmmod -a"?
It's better to unload the unused modules because our embedded system doesn't
have much memory.
Regards,
Colin

Hi all,

I use 2.6 kernel and found that "rmmod -a" doesn't work any more.
Why do you want to do that? How do you know if a module is being used
or not (hint, the usb drivers and network drivers do not increment their
usage count when in use, unloading them can render a machine pretty
dead...)
good luck,
greg k-h
And its not just network drivers (IIUC)
The module usage count only counts uses/dependencies of other modules,
userspace deps are *not* counted.
ForEx:
$ lsmod |grep '0 $'
radeon 106849 0
battery 9413 0
ohci1394 35205 0
uhci_hcd 32465 0
ohci_hcd 21981 0
I can assure you that I am currently using the screen driven by the
radeon driver.
