traversing module trees

traversing module trees

[Jacob Schmude]

Hi all
 	Is ther a way of removing one module and having the kernel remove 
all the modules associated with it? An example, if I do:
rmmod usbcore
 	I'd like all the other USB modules to be unload before usbcore is. 
Can this be accomplished? I'm working with kernel 2.6.6.

Try modprobe -r usbcore. That will do what you want and if you have
forced module unloading in your kernel it will even ignore module
dependencies.

Hi
	modprobe -r didn't work. It simply said the module was in use. 
What I want is a way to figure out what modules are using that, unload 
them, then unload the module I specified. If I had to compare it to 
anything, it would be an apt-get remove operation. You do apt-get remove 
xlibs and all the packages that depend on xlibs, and all packages that may 
have depended on those, are removed as well. This is what I want for 
modules, and looking through lsmod output manually won't work, since I 
need to do this in a script which will eventually be used for ACPI's 
suspend feature. I've looked on google but haven't found anything. Any 
ideas? I don't want module dependencies ignored, I want them followed.
