Subject: [PATCH] selinux: Fix SBLABEL_MNT for NFS mounts
Labelling of files in a NFSv4.2 currently fails with ENOTSUPP because
the mount point doesn't have SBLABEL_MNT.
Add specific condition for NFS4 filesystems so it gets correctly
labeled.

Hi,
cannot remotely say that I currently understand how selinux is expected
to work within NFS mounts, but this change allowed me to fully boot AOSP
with its rootfs and ramdisk on a single NFS share.
Thanks,
Tomeu
