OK, this is what I did: Split the set into 3, in the following order: CORE -> DRIVERS -> ARCH So that's 3 branches, core is based off master, drivers off core, and arch off drivers. I'll push core+drivers into #for-akpm for testing, then the arch bits will stay undisturbed until acked by maintainers. -- Jens Axboe - 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/

Doing it around the -rc1 time would be better. Even better would be not doing it at all: add the necessary stuff into the block core and then send the followup work to the relevant maintainers. ie: standard practice. I'll keep rebasing sglist and the other branches I pull into for-akpm, so you can just re-enable the for-akpm pull when the a) is true. Andi's tree is very out of date and is about to be damaged (to what extent I don't yet know) by a xen merge. I don't know if a) is going to happen. Things are more than usually messy this time around. - 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/

The Xen and Calgary bits are mutually exclusive, so hopefully (a) will not be held up on account of the Xen merge (or for any other reason... CalIOC2 machines which are out there won't boot without it if CONFIG_CALGARY_IOMMU is enabled).
