No problem, I fixed it and repushed the pci/enhanced-allocation branch: https://git.kernel.org/cgit/linux/kernel/git/helgaas/pci.git/log/?h=pci/enhanced-allocation -- To unsubscribe from this list: send the line "unsubscribe linux-api" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
