I only did this bc there's an existing option called FEATURE_MOUNT_NFS and it mentioned

the Linux kernel version and I want to make as few changes as possible. The best option

would obviously be renaming the existing FEATURE_MOUNT_NFS to something like

FEATURE_MOUNT_NFS_LEGACY and make FEATURE_MOUNT_NFS a main switch.
