https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=294039 --- Comment #7 from Konstantin Belousov <kib@FreeBSD.org> --- (In reply to Peter Much from comment #6) If you are so sure that this change causes problems, you should run the HEAD kernel with INVARIANTS enabled and sysctl debug.vm_check_pg_zero set to true. 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 dump to analyze. The change you blame makes the new mapped page to be zeroed in more cases than without the change, but the situation where this happen is quite rare. -- You are receiving this mail because: You are the assignee for the bug.home | help
