Summary: https://github.com/facebook/rocksdb/pull/3881 fixed a bug where PinnableSlice pin mmap files which could be deleted with background compaction. This is however a non-issue for ReadOnlyDB when there is no compaction running and max_open_files is -1. This patch reenables the pinning feature for that case. Closes https://github.com/facebook/rocksdb/pull/4053 Differential Revision: D8662546 Pulled By: maysamyabandeh fbshipit-source-id: 402962602eb0f644e17822748332999c3af029fd
