What were you trying to do that didn't work?

A resource structure in lvmlockd for an LV that had at one point been locked, will never be freed, even if that LV has been freed.  If many LVs are created and removed over time, an excessive number of unused structures creating long lists and wasted memory will accumulate.  This requires redesigning the structure lifetime logic.  A prerequisite for fixing this is cleaning up the command-side lvmlockd calls (RHEL-74276) to eliminate extraneous operations on resources which would unnecessarily recreate structures after they have been freed.
