Details

In tbb 2021 name of some protected members in tbb:spin_rw_mutex::scoped_locke were change (is_write -> m_is_write). Since we use them in concurrent_hash_map in tests with tbb there is a compilation error.

[pbalcer]

ideally, you'd remove the dependency on internal variables entirely since the alternative approach would be to include a compile-time version check.

[igchor]

Yes, tbb should expose a public interface to query for the information we need (whether the lock is in read or write mode).
