Actually it is dependent on IPC_NS since it makes changes to ipc/namespace.c which is compiled only if CONFIG_IPC_NS. There are a couple more implementations similar to this one. https://lwn.net/Articles/577957/ and some submissions to AOSP derived from that one that introduce a generic registration function for namespace support [1], and changes to binder to implement namespaces [2]. If this is really needed, then we should have a solution that works for devices without requiring IPC_NS or SYSVIPC. Also, we should not add binder-specific code to ipc/namespace.c or include/linux/ipc_namespace.h. -Todd [1] https://android-review.googlesource.com/c/kernel/common/+/471961 [2] https://android-review.googlesource.com/c/kernel/common/+/471825 _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
