6.18.x rust_binder affecting Waydroid

Description:

After updating Arch Linux to the latest kernel 6.18.1.arch1-2, Waydroid stopped working properly. The session starts, but audio is partly broken. Specifically, some audio that uses the system stack (like OMX? I apologize, I'm not very familiar with Android) cannot be played, such as the built-in music app. However, apps like VLC can play the audio. The log shows: E/WOmxObserver-impl( 213): LWOmxObserver::onMessages - Transaction failed.

When I downgraded the kernel to 6.17.9-arch1-1, this problem disappeared.

I looked at the Arch Linux build options and suspect the following section is the cause. After I changed these parameters back to their original values ​​from the previous version, Waydroid started working correctly.
