For st_dev in struct stat, the value 0 is an error. Make sure rootfs has value 1. This fixes the coreutils cp -ax issue (although that code has already been improved in coreutils, too) and somewhat fixes the switch_root problem in util-linux. It is still possible that rootfs gets an FSID >1 in future versions, so util-linux still needs to be fixed. This is unrelated to the mount id issue in /proc/*/mountinfo - the mount id may still be zero. * Revert a patch that always enables autosuspend on intel bluetoothh xhci still sucks and breaks this. I am reverting this commit for reasons that are in no way selfish.
