commit 8cba03537fac8f27c041bbaf4067630e66e752e6 Author: Julius Werner jwerner@chromium.org Date: Thu Feb 5 12:55:45 2015 -0800
elog: Fix regression that caused elog to omit "System boot" event
CL:243671 moved the initialization of elog_initialized around, which is now unfortunately so late that the ELOG_TYPE_BOOT event gets omitted because the code believes the log to be broken at that time. Good thing we now have a FAFT test for these things that I had of course been too lazy to run. -.-
The real reason for moving that line was to put it after any point in elog_init() that could still error out. The problem is that we might add the "cleared" event before we try to shrink (which can fail and cause an error)... but those two things cannot happen at the same time, so it should be okay to flip them around and mark the elog as initialized in between.
BRANCH=none BUG=chrome-os-partner:35940 TEST=Ran firmware_EventLog on a Pinky, manually confirmed that I once again get "System boot" events.
