I am just about done with all the features of tmpfs -- just basically
have debugging now to do. Anyway, I wanted to make it more efficient
by only storing non-buffer-cached chunks of files on disk. Reading
the buffer cache is no problem. However, can anyone give me some
hints on how I should "catch" a page as it is being "expired", and
write that segment out to tmpfs memory?
