Hi,
When I try to add the function in dev.c and compile, I get the message
saying undefined reference to `driver_control'. Am I missing something
here?. Looks like liking is not happening properly. Should I add any header
files in dev.c?
Thanks/Sanjay

This should do it! just call this from whatever kernel program u want
to....it should wrk i guess....unless i'm missing something very
obvious! have you tried calling "driver_control" from dev.c ?? U've
exported the symbol correctly (not sure of the _NOVERS thing)....so any
kernel module should be able to call it........
