Previously, if the priority is same, devlinks are always replaced by newer events. The commit331aa7aa15changes that to keep the existing devlink. That should not change any behavior when the devices that request the same symlink do not have any dependency, e.g. when /dev/sda1 and /dev/adb1 request the same /dev/disk/by-label symlink, as there are no guarantee that which device is processed first. However, when devices has dependency, e.g. /dev/sda and /dev/sda1 request the same /dev/disk/by-label symlink, previously the symlink always pointed to the partition, as the partition is always processed later. But,331aa7aa15makes the symlink point to the whole disk. The change by331aa7aa15is crucial to improve performance of devlink handling, especially when a system has large number of disks with same label or so. Hence, cannot and should not be reverted. So, let's workaround the case, as such situation should happen only when the disk is a hybrind ISO image, I guess. Fixes #28468.
