I think the reason it was dropped was because it was part of a large patch series that didn't make it into the kernel. And unfortunately, this was dropped in that regard. If you do pull this patch in, I would like to get a sign-off-by from Dipankar and give him credit, since I think he was the original author. I just pulled it out of the -rt branch. -- Steve - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
