I mean that "MemFree" should be called something like "MemInactive" and "MemAvailable" should be called "MemFree" in /proc/meminfo. Some things in Linux are poorly named, with caveats in the documentation saying "Oh but not all free memory is free." It's a pretty minor complaint. There's also the 30 year old bug where there's nothing stopping any userspace non-root program from totally locking up a machine by allocating all the RAM, which causes the kernel to constantly swap pages to disk and back and freezes the whole system. Buut that's another issue really.
