Hm, a few days ago I had high memory usage that free showed as cache, but I didn't find it anywhere in any of my tmpfs mounts and going to rescue.target cleared it. I just had the thought that maybe there were files in a tmpfs that got marked deleted so I didn't see them... As long as a process has it open / a link in /proc/pid/fd/, it will still be displayed as cached, right?
