It = will catch the situation where the fresh anonymous page is non-zero. If the checker detects the problem, it panics and we should get the core du= mp to analyze. The change you blame makes the new mapped page to be zeroed in more cases t= han without the change, but the situation where this happen is quite rare. --=20 You are receiving this mail because: You are the assignee for the bug.=
