Those brave Fedora-rawhide testers have also hit an assortment of slab

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.
