From: Miklos Szeredi <mszeredi@suse.cz>

3.4.108-rc1 review patch. If anyone has any objections, please let me know.

------------------

commit aa991b3b267e24f578bac7b09cc57579b660304b upstream.

Regular pipe buffers' ->steal method (generic_pipe_buf_steal()) doesn't set
PG_uptodate.

Don't warn on this condition, just set the uptodate flag.
