Those brave Fedora-rawhide testers have also hit an assortment of slab
related errors recently, manifesting in various ways including our old
friend the negative page_mapcount.

From that report, the page flags indicate that the page is regular
old pagecache. I'd be very surprised if there is a mapcount bug here.
It looks like something is scribbling in memory, which I would
suspect first.
However if you do see new mm/rmap bugs, do keep posting them so we
can see if there is a pattern.
