According to the README, "The tikv-jemallocator crate re-exports the features of the tikv-jemalloc-sys dependency".

tikv-jemalloc-sys has a feature flag called disable_cache_oblivious, but it including it in the tikv-jemallocator entry in Cargo.toml leads to an error, because it looks like it does not actually re-export the feature.

Is this intentional? Can the feature be used by including tikv-jemalloc-sys directly in the project? Or does it need to be fixed?
