Hi,
Here is a pair of patches which adds --lockup option to modprobe and libkmod.
As I sent a series of patches which removes stop_machine() from module removal: https://lkml.org/lkml/2014/8/25/142 it also adds lockup option which lock up the module in the kernel and makes it un-removable.
These patches enables us to use that option when loading modules. Module lockup may be good for BIG SMP machines since the kernel skips module refcounting if the module is locked up :)
Anyway, this is not needed if the lockup option is dropped from the series. I send this for testing.
Thank you,
