https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D275436 Konstantin Belousov <kib@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |kib@FreeBSD.org --- Comment #1 from Konstantin Belousov <kib@FreeBSD.org> --- I do not think this is a right approach. Free pages/free target from the VM subsystem is not what people usually think about it. The numbers only dire= ct the pagedaemon activity, they are not indicative in any other way. If the system has enough swap and inactive pages, they can be converted into reusa= ble pages without causing OOM/ENOMEM etc. Similarly, I do not think it is right to do any limiting on tmpfs file resi= ze. Tmpfs supports holes, and there is no reason to block that. Tmpfs already has the mechanism to count actually allocated pages and to cl= amp the amount of pages allocated to specific mount. It it the right thing to = do IMO. Why wouldn't you use it? --=20 You are receiving this mail because: You are the assignee for the bug.=
