Hi,
I am facing an issues with module unloading,
I have two modules say A, B
A depends on B, so B is automatically loaded when A is loaded.
B module is also directly being used by the user side code via misc interface.
Now when I am unloading module A, via "modprobe -r A" it is also unloading the module B which is being used by the application and resulting in the kernel crash.
Also, lsmod ouput shows driver B is not used by anybody. Seems "Used By" of lsmod output is not getting updated.
How to prevent unloading of module B in used. When unloading module 'A' via modprobe -r
Thanks,
Chetan Nanda
