https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D276002 --- 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 fr= om the existing mappings, allowing writers to continue write to the file mappi= ngs. I think that this allows more mapped writes to be lost. --=20 You are receiving this mail because: You are the assignee for the bug.=
