https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=276002 --- Comment #22 from Konstantin Belousov <kib@FreeBSD.org> --- (In reply to Rick Macklem from comment #21) It would be very strange if this patch helped. More, I think it is somewhat dangerous because it can cause data corruption on itself. Issue is, not clearing pages dirty bits also does not remove write perms from the existing mappings, allowing writers to continue write to the file mappings. I think that this allows more mapped writes to be lost. -- You are receiving this mail because: You are the assignee for the bug.help
