Description:
Info
With the backport to 6.0 of SERVER-79049 we had to disable the jstests/sharding/swallow_unnecessary_uuid_mismatch_error.js test in the sharding_batched_deletes_passthrough suite. This is because instead of returning the expected number of documents deleted to be 3 it instead returns 4. Note that it doesn't actually affect the end result. A simple scan of the collection afterwards returns the full collection only containing 3 documents less. This is instead a problem of misleading results. It's also not happening on 7.0+.
