More or less. But part of it also is that a lot of the patches I've written are on top of other patches that people don't want (aka, the iorl patch). I've got a mlqueue patch that actually *really* should go into mainline because it solves a slew of various problems in one go, but the current version of the patch depends on some semantic changes made by the iorl patch. So, sorting things out can sometimes be difficult. But, I've been told to go ahead and do what I can as far as getting the stuff out, so I'm taking some time to try and get a bk tree out there so people can see what I'm talking about. Once I've got the full tree out there, then it might be possible to start picking and choosing which things to port against mainline so that they don't depend on patches like the iorl patch. -- Doug Ledford 919-754-3700 x44233 Red Hat, Inc. 1801 Varsity Dr. Raleigh, NC 27606 - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
