You could just use for-3.7/core as of today, there's not that much in there yet. Alternatively, I'd have to rebase for-3.7/core and rip them out, put them in a separate branch, and pull that back into for-3.7/core. -- Jens Axboe -- To unsubscribe from this list: send the line unsubscribe linux-scsi in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
