I tried that.  The error is coming from fs/dcache.c, and it does look like
including that file is a good idea, but no matter where I put the #include
directive, I still get the same error.

Strange.  While adding a #include for <linux/spinlock.h> didn't work,
tossing in the #define for atomic_dec_and_lock() did the trick.

So now in fs/dcache.c, I have:


#include <linux/cache.h>
#include <linux/module.h>

#include <asm/uaccess.h>
#define atomic_dec_and_lock(atomic,lock) atomic_dec_and_test(atomic)

#define DCACHE_PARANOIA 1
/* #define DCACHE_DEBUG 1 */



I know that this isn't the right fix; hopefully that will be in -pre5.
Well, now that it compiles, it's time to boot...

After making the patch to setup.c so that it would compile, I ran into a
linking error.  I have a fairly standard uniprocessor PIII system.  I can
make my config file available to anyone that thinks it will help.

Assuming that your version is similar to mine....

In ...linux/fs/dcache.c add ...
#include <linux/spinlock.h>
