3.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Kent Overstreet <kmo@xxxxxxxxxxxxx>
commit 6d9d21e35fbfa2934339e96934f862d118abac23 upstream.
That switch statement was obviously wrong, leading to some sort of weird
spinning on rare occasion with discards enabled...
