Summary: Fixes https://github.com/facebook/rocksdb/issues/5734. By reading the code the assert don't quite make sense to me, since `dataSize` and `fileOffset` has no correlation. But my knowledge about `EncryptedEnv` is very limited. Pull Request resolved: https://github.com/facebook/rocksdb/pull/5735 Test Plan: run `ENCRYPTED_ENV=1 ./db_encryption_test` Signed-off-by: Yi Wu <yiwu@pingcap.com> Differential Revision: D17133849 fbshipit-source-id: bb7262d308e5b2503c400b180edc252668df0ef0
