Scale tests have identified the lflow cache to be one of the main memory
consumers in ovn-controller. This series refactors the lflow cache code
and adds configuration knobs to limit the size (in lines and/or memory)
of the cache.
Dumitru Ceara (6):
lflow: Refactor convert_match_to_expr() to explicitly consume prereqs.
lflow-cache: Move the lflow cache to its own module.
lflow-cache: Add coverage counters.
lflow-cache: Reclaim heap memory after cache flush.
lflow-cache: Make maximum number of cache entries configurable.
lflow-cache: Make max cache memory usage configurable.
