Also the current system call interface to the memory statistics does
not return the size of the "page cache". You can see this if you look
into fs/proc/array, where /proc/meminfo is implemented. I had pointed
this out once before; the meminfo system call (I can't remember it's
name right now) returns a structure that should be either expanded to
include the page_cache, or the page_cache should be added to the
buffers (which is worse in my opinion).
I'd also suggest to add a paragraph to the README that explains how
to (cross-)compile an a.out kernel on an ELF system. I configured it
correctly, and the Makefile in arch/i386 seems to take care of the
configuration variables, but it did not work:
An undefined symbol "_start" and about three (sorry, no typescript)
other undefined symbols when linking. I need a newer kernel for a
tiny a.out system.
