Subject: [PATCH 3.19 038/123] fuse: set stolen page uptodate

3.19-stable review patch.  If anyone has any objections, please let me know.

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

From: Miklos Szeredi <mszeredi@...e.cz>

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.
