In linux kernel since version 5 (release Date: 2019-03-03)  
Binderfs is a pseudo-filesystem for the Android Binder IPC driver
which can be mounted per-ipc namespace allowing to run multiple
instances of Android.
Each binderfs mount initially only contains a binder-control device.
It can be used to dynamically allocate new binder IPC devices via
ioctls.
