Uh, I'm not sure we should do this. If this only affects cgroup v1 then I say we should simply not care at all. It's a deprecated api and anyone using it uses something that is inherently broken and a big portion of userspace has already migrated. The current or upcoming systemd release has dropped all cgroup v1 support.

I am not quite sure if nfs will be affected by this or not. It looks like vfs_get_tree -> nfs_get_tree -> nfs_try_get_tree -> nfs_try_get_tree -> nfs_request_mount -> nfs_mount -> rpc_call_sync -> rpc_run_task -> rpc_execute -> __rpc_execute -> rpc_wait_bit_killable might return -ERESTARTSYS.
