Actually they are LGPL, according to other posts in this thread. Which would make it perfectly OK.<p>I&#x27;m not well enough traversed in the kernel source to find a direct reference but you see commits like this every now and then:<p><a href="https:&#x2F;&#x2F;git.kernel.org&#x2F;cgit&#x2F;linux&#x2F;kernel&#x2F;git&#x2F;torvalds&#x2F;linux.git&#x2F;commit&#x2F;?id=09a77a885233e2a20dac2635a79c83ccf50a26a1" rel="nofollow">https:&#x2F;&#x2F;git.kernel.org&#x2F;cgit&#x2F;linux&#x2F;kernel&#x2F;git&#x2F;torvalds&#x2F;linux....</a><p>Having parts of the kernel LGPLed doesn&#x27;t seem like an unusual or odd thing, from what I can tell:<p><a href="https:&#x2F;&#x2F;git.kernel.org&#x2F;cgit&#x2F;linux&#x2F;kernel&#x2F;git&#x2F;torvalds&#x2F;linux.git&#x2F;log&#x2F;?qt=grep&amp;q=lgpl" rel="nofollow">https:&#x2F;&#x2F;git.kernel.org&#x2F;cgit&#x2F;linux&#x2F;kernel&#x2F;git&#x2F;torvalds&#x2F;linux....</a>
