Summary: There is a race in SstFileManagerImpl between the ClearError() function and CancelErrorRecovery(). The race can cause ClearError() to deref the file system pointer after it has been freed. This is likely to occur during process shutdown, when the order of destruction of the DB/Env/FileSystem and SstFileManagerImpl is not deterministic. Pull Request resolved: https://github.com/facebook/rocksdb/pull/9435 Test Plan: Reproduce the crash in a TSAN build by introducing sleeps in the code, and verify with the fix.

RocksDB: A Persistent Key-Value Store for Flash and RAM Storage
RocksDB is developed and maintained by Facebook Database Engineering Team. It is built on earlier work on LevelDB by Sanjay Ghemawat (sanjay@google.com) and Jeff Dean (jeff@google.com)
This code is a library that forms the core building block for a fast key-value server, especially suited for storing data on flash drives. It has a Log-Structured-Merge-Database (LSM) design with flexible tradeoffs between Write-Amplification-Factor (WAF), Read-Amplification-Factor (RAF) and Space-Amplification-Factor (SAF). It has multi-threaded compactions, making it especially suitable for storing multiple terabytes of data in a single database.
