Summary: Pull Request resolved: https://github.com/facebook/rocksdb/pull/12347 `DBImpl::disable_delete_obsolete_files_` should only be accessed while holding the DB mutex to prevent data races. There's a piece of logic in `DBImpl::RenameTempFileToOptionsFile` where this synchronization was previously missing. The patch fixes this issue similarly to how it's handled in `DisableFileDeletions` and `EnableFileDeletions`, that is, by saving the counter value while holding the mutex and then performing the actual file deletion outside the critical section. Note: this PR only fixes the race itself; as a followup, we can also look into cleaning up and optimizing the file deletion logic (which is currently inefficient on multiple different levels).
