I have inserted my network driver module (netdrv.ko). When I try to remove the module using rmmod, it is displaying "killed". When I checked with lsmod, the module is not removed. So, I tried rmmod again, thereby its displaying
"ERROR: Removing 'netdrv': Device or resource busy"
I also tried modprobe command(modprobe -rf netdrv). The message shown is
FATAL: Module netdrv not found.
How can I remove the module without restarting.
