22   - store data needed to manipulate and restore the system state
24   - define compatibility between livepatches using a change id
44   - *id*
46     - Non-zero number used to identify the affected system state.
48   - *version*
50     - Number describing the variant of the system state change that
55   - klp_get_state()
57     - Get struct klp_state associated with the given livepatch
60   - klp_get_prev_state()
62     - Get struct klp_state associated with the given feature id and
71   - Any completely new system state modification is allowed.
73   - System state modifications with the same or higher version are allowed
76   - Cumulative livepatches must handle all system state modifications from
79   - Non-cumulative livepatches are allowed to touch already modified
85 Livepatches have their life-cycle and the same is true for the system
89   - Modify the system state when the livepatch gets enabled and the state
93   - Take over or update the system state modification when is has already
96   - Restore the original state when the livepatch is disabled.
98   - Restore the previous state when the transition is reverted.
102   - Remove any already made changes when error occurs and the livepatch
113   - Allocate *state->data* when necessary. The allocation might fail
115     of the livepatch. The allocation is not needed when the data
118   - Do any other preparatory action that is needed by
120     For example, initialize *state->data*.
125   - Clean up its own mess in case of error. It might be done by a custom
130   - Copy *state->data* from the previous livepatch when they are
133   - Do the actual system state modification. Eventually allow
136   - Make sure that *state->data* has all necessary information.
138   - Free *state->data* from replaces livepatches when they are
143   - Prevent the code, added by the livepatch, relying on the system
146   - Revert the system state modification..
150   - Distinguish transition reverse and livepatch disabling by
153   - In case of transition reverse, restore the previous system
156   - Remove any not longer needed setting or data.
166    It might be called also during the transition reverse. Therefore it
