Inserting modules w/o version check

Inserting modules w/o version check

[Mathew, Tisson K]

All ,

Can we enforce no version check for modules when they are inserted ( insmod
) ? If yes , can this be implemented in the module itself ?

Thanks in advance

No. `insmod` wouldn't load it so the module doesn't get a chance to
"check" anything.

Also, note that `struct file_operations` has different member-
locations for different kernel versions. Even if the module
loaded, you might end up with 'read' being 'seek', etc. Bad idea.

no

but it's much nicer to make a "lazy compile" option so that if the
kernel 
doesn't match you compile a new module from source on demand....
It's not hard to do...

insmod -f, but don't bother sending bug reports to l-k after a forced
insert.
