vfs: force reval of target when following LAST_BIND symlinks (try #7)
procfs-style symlinks return a last_type of LAST_BIND without an actual path string. This causes __follow_link to skip calling __vfs_follow_link and so the dentry isn't revalidated. This is a problem when the link target sits on NFSv4 as it depends on the VFS to revalidate the dentry before using it on an open call. Ensure that this occurs by forcing a revalidation of the target dentry of LAST_BIND symlinks. Signed-off-by: Jeff Layton <jlayton@redhat.com> Acked-by: "Eric W.
