Summary: There was a bug in the MultiGet enhancement in https://github.com/facebook/rocksdb/issues/9899 with data block hash index, which was not caught because data block hash index was never added to stress tests. This change fixes both issues. Fixes https://github.com/facebook/rocksdb/issues/10186 I intend to pick this into the 7.4.0 release candidate Pull Request resolved: https://github.com/facebook/rocksdb/pull/10220 Test Plan: Failure quickly reproduces in crash test with kDataBlockBinaryAndHash, and does not seem to with the fix. Reproducing the failure with a unit test I believe would be too tricky and fragile to be worthwhile.
