binderfs support is not enabled

[Simon Fels]

[Impact]

Hey,

in https://bugs.launchpad.net/ubuntu/+source/linux-azure/+bug/1914568 we got binder support enabled but the configuration is completely different from what we have in our other cloud and generic kernels:

ubuntu@machine-1:~$ cat /boot/config-5.4.0-1046-azure | grep BINDER
CONFIG_ANDROID_BINDER_IPC=m
# CONFIG_ANDROID_BINDERFS is not set
CONFIG_ANDROID_BINDER_DEVICES="binder,hwbinder,vndbinder"
# CONFIG_ANDROID_BINDER_IPC_SELFTEST is not set

$ cat /boot/config-5.4.0-14-generic | grep BINDER
CONFIG_ANDROID_BINDER_IPC=m
CONFIG_ANDROID_BINDERFS=m
CONFIG_ANDROID_BINDER_DEVICES=""
# CONFIG_ANDROID_BINDER_IPC_SELFTEST is not set

Not having binderfs support is breaking Anbox Cloud support. What is the reason for not having the config aligned between the kernels here?

Thanks!

[Test Plan]

After installing the extra modules package, binderfs should be available via mount.

[Where problems could occur]

It could cause issues to any existing users of the existing binder_linux module. However this module is currently shipped as extra and should not affect regular users.

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-hirsute' to 'verification-done-hirsute'. If the problem still exists, change the tag 'verification-needed-hirsute' to 'verification-failed-hirsute'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
