The Linux developers involved use the CDDL. While some of them have patches in Linus’ tree, most of them are described as Linux developers because they develop and use the code on Linux. They have little to do with mainline Linux, partly because certain the mainline Linux developers will actively go out of their way to antagonize them if they even try to contribute to mainline. Certain others will simply ignore their emails. I will not say names, but I have had that happen to me in the past.

That said, I suspect you did not read the replies, since the code in question was written by a FreeBSD developer. Bugs in new code have been introduced by developers on both platforms. Unfortunately, the bugs in this feature were not caught before they reached a stable release. :/
