I prefer that the warnings > always are removed. No, I do not. They have found a lot of real bugs that have been going unnoticed for quite some time, and some new ones (like the current mess in the pci hotplug subsystem where two different drivers are controlling the same pci hotplug slots and not realizing it at all.) So having the warning gone for rename() is fine, but I still want it there for new files that are being added to the system. thanks, greg k-h
