From 9f78ff005a6b6313728247113948450b2adddde8 Mon Sep 17 00:00:00 2001 From: Stephen Boyd Date: Mon, 5 Mar 2012 14:59:17 -0800 Subject: [PATCH] debugobjects: Fix selftest for static warnings debugobjects is now printing a warning when a fixup for a NOTAVAILABLE object is run. This causes the selftest to fail like: ODEBUG: selftest warnings failed 4 != 5 We could just increase the number of warnings that the selftest is expecting to see because that is actually what has changed. But, it turns out that fixup_activate() was written with inverted logic and thus a fixup for a static object returned 1 indicating the object had been fixed, and 0 otherwise. Fix the logic to be correct and update the counts to reflect that nothing needed fixing for a static object.
