If "the filesystem knows that if it needs X amount of space for a file,"
that implies there's a way of telling it that.
How's that done? I don't recall any system call for *x (there is one for
OS/2), and one could do it in JCL in IBM's OS in the 60s), but in the *x
world I've never seen a way to do it.
