randomly wondering: Are there file systems that support auto-freeing cache files on demand when disk space runs low? Like how, in memory management, there are ways to mark memory as "please discard these pages/mappings if the OS wants more RAM"?

In memory management, people say "free space is wasted space", and while I know SSDs and free space are a complicated topic, it kinda seems like the idea should also work for disks to some extent?
