From 0a22f485eee6ae8da77c3e37c8856e025678cdb0 Mon Sep 17 00:00:00 2001 From: Kent Overstreet Date: Mon, 23 Sep 2013 23:17:27 -0700 Subject: bcache: Fix a dumb journal discard bug commit 6d9d21e35fbfa2934339e96934f862d118abac23 upstream. That switch statement was obviously wrong, leading to some sort of weird spinning on rare occasion with discards enabled...
