Subject: Re: Support for 5.7 linux kernel?
Hey,
Can you double check if you have enabled CONFIG_MODULE_UNLOAD ?
I've checked the sources here (latest 5.7):
https://elixir.bootlin.com/linux/v5.7-rc7/source/include/linux/module.h#L501
and missing variable is under #ifdef CONFIG_MODULE_UNLOAD block.
Thanks,
Adam
