- we have these levels when the udev rules are processed: 10-dm.rules --> [11-dm-<subsystem>.rules] --> [12-dm-permissions.rules] --> 13-dm-disk.rules --> [...all the other foreign rules...] --> 95-dm-notify.rules - each level can be disabled now by DM_UDEV_DISABLE_{DM, SUBSYSTEM, DISK, OTHER}_RULES_FLAG - add DM_UDEV_DISABLE_DM_RULES_FLAG to disable 10-dm.rules - add DM_UDEV_DISABLE_OTHER_RULES_FLAG to disable all the other (non-dm) rules. We cutoff these rules by using the 'last_rule', so this one should really be used with great care and in well-founded situations. We use this for lvm's hidden and layer devices now. - add a parameter for add_dev_node, rm_dev_node and rename_dev_node so it's possible to switch on/off udev checks - use DM_UDEV_DISABLE_DM_RULES_FLAG and DM_UDEV_DISABLE_SUBSYSTEM_RULES_FLAG if there's no cookie set and we have resume, remove and rename ioctl. This could happen when someone uses the libdevmapper that is compiled with udev_sync but the software does not make use of it. This way we can switch off the rules and fallback to libdevmapper node creation so there's no udev/libdevmapper race. |
