but, but, but...   That's on-disk size.

What does /usr/bin/size say?

And don't forget http://www.zip.com.au/~akpm/linux/2.4/2.4.17-pre1/inline.patch
which deletes 61 `inline's and save 12 kbytes.  We really, really

sloshing squigabytes of instructions across the external memory bus
quite unnecessarily.
