Might be b52723c5 did not fix the problem fully? > When a bisect identifies a commit in between a known-broken patch and fix for that broken patch, you need to revert your tree back to the fix (b52723c5) and retest. If the problem persists, then 696d3cd5 is the bad commit. Otherwise, you need to bisect between the fix (by labeling it with "git bisect good") and HEAD. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
