hi,
i created a sample module and while trying to insert it i am getting the message "Killed". But when I did lsmod my module was listed out there and was 'Used by' 1. Maybe because it is in use I cannot do a rmmod on my module. How to overcome this, that is do a rmmod while it is still in use?

Hi,

might be worth trying

modprobe -r

or

modprobe -rf

instead of rmmod, also there could be a service that uses the 'in use' module you may have to stop that first then try to remove it.

HTH

ok..i will try using modprobe.
pl tell me this also.. how to know which service is using the current module and how to stop it from using that module?

Certainly - if the modprobe doesn't work then post the output of your lsmod and highlight the module you are having the problem with i should be able to tell, some are obvious from their name others require a bit of digging around. eg. on my system if i had the problem trying to remove the ip_tables module (for example) :

lsmod

ip_tables 21953 4 iptable_raw,iptable_mangle,iptable_nat,iptable_filter

I would run:

/etc/init.d/iptables stop

then

modprobe -r ip_tables

Hope this makes sense, usually the modprobe -r removes the module and its dependants.
