While the second call to dm_cache_metadata_abort is\ncaused by lack of support for table preload in dm-cache, mentioned\nin commit 9b1cc9f251af (\"dm cache: share cache-metadata object across\ninactive and active DM tables\"), it exposes the memory leak in\ndm_cache_metadata_abort when the function is called multiple times.\nSpecifically, dm-cache fails to sync the new cache object's mode during\npreresume, creating the reproducer condition.\n\nThis issue could also occur through concurrent metadata_operation_failed\ncalls due to races in cache mode updates, but the table preload scenario\nbelow provides a reliable reproducer.\n\n1.
