Hello all,

two questions (I am new to the backports project):

If I configure backports to build a driver as a module, whilst the 
kernel we build against (KLIB/KLIB_BUILD) has this driver built-in, what 
is supposed to happen?

Obviously I cannot load the backport module into the kernel.


Is it possible (within the kernel and backports code) to build a 
subsystem or driver as a module, if the original kernel did not have 
this subsystem or driver built at all ("N" in the menu, CONFIG_ 
commented out in .config)?

Can the kernel always load modules that were defined as =N during the 
kernel built itself?

(My aim is Yocto/OpenEmbedded support for backports into the build system.)

Thanks,

Leon.
