[Greg Kroah-Hartman]

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

From: Alexander Aring <aring@xxxxxxxxxxxx>


[ Upstream commit f6cd14537ff9919081be19b9c53b9b19c0d3ea97 ]

We need to record stats for received metadata that we dont know how
to process. Have find_decode_metaid() return -ENOENT to capture this.
