Quite true, but is there any other subsystem where we know we have bugs and have put up such a scary warning? I've never used ZFS on i386, but I understand it is trivial to panic with out-of-the-box settings. We don't print a dire warning for ZFS usage on 32-bit platforms. So I'm not sure we should keep it for TMPFS. I cannot tell from your response if you're OK or against removing the warning. [especially if your patches pass the Peter Holm test and remove some of the bugs] -- -- David (obrien@FreeBSD.org)
