heh. inodes are not too large anyway; you can fit 12 of them onto a
page. i don't see much advantage of actually shrinking the inode cache
the same way the buffer cache is shrunk. i tried a couple of little
experiments that suggested such a thing could only be bad for performance.
back to the memory leak. i think the late 2.3 kernels don't swap as
aggressively as earlier kernels did, and thus a lot of useful cached state
is shrink_mmap()'d away. even the 2.2 kernels don't swap as hard as they
ought to, IMO.
