Thanks for the review. I tend to disagree. The ordering issue is there for a long time and not introduced by a8492e25ac71 so "Fixes" tag is not accurate.

I agreed with you that "a8492e25ac71 triggered the bug, not introduced the bug" but this patch obviously add a fix for " a8492e25ac71 " so IMHO there is nothing wrong to add Fixes tag in this patch.
