High-performance synchronization primitives compatible with Windows NT kernel API. Internal to performance category.
NTSync brings Windows-compatible synchronization primitives (such as those used by NT kernel objects) to the Android kernel, which can be useful for compatibility with software expecting Windows-style synchronization behavior.
It is documented as internal to the performance category.
NTSync is enabled via the use_ntsync feature flag in the build workflow. It is enabled by default.
