[lizf: Backported to 3.4:
- remove the changes to follow_link() as it doesn't call set_root()]
looks dubious - I don't have -stable in front of me, but set_root() in
follow_link() had migrated from __vfs_follow_link(), so could you try
(tr '#' '\t' | ed fs/namei.c) <<'EOF'
/__vfs_follow_link/
/set_root/s/^/#/
i
##if (!nd->root.mnt)
.
wq
EOF
and see if it helps?
