Subject: lve module taint?

Hi all,

        I still have this patch sitting in my queue for next merge
window; I missed the previous one.  Is it still current?

Thanks,
Rusty.

Subject: module: taint kernel when lve module is loaded
Date: Fri, 22 Jun 2012 13:49:31 -0400

Cloudlinux have a product called lve that includes a kernel module. This
was previously GPLed but is now under a proprietary license, but the
module continues to declare MODULE_LICENSE("GPL") and makes use of some
EXPORT_SYMBOL_GPL symbols. Forcibly taint it in order to avoid this.
