hi guys;

i was wondering is there a way to forcefully unload a module.i have written this module and everytime i try to unload it (rmmod my_module),it says Device or resource busy.

any comments would be helpful.

'man rmmod' turns up this:

Code:

       -f --force
                 This option can be extremely dangerous:  it  has
                 no  effect unless CONFIG_MODULE_FORCE_UNLOAD was
                 set when the kernel  was  compiled.   With  this
                 option,  you  can remove modules which are being
                 used, or which are not designed to  be  removed,
                 or have been marked as unsafe (see lsmod(8)).
