PATCH 1/1 shmem fixes for 2.4.1-pre7

Hi Linus,

Here is a patch against 2.4.1-pre7 which

1) Adds prototype for shmem_lock to mm.h
2) Again brings the fixes for the accounting. I still think it should be applied.

Greetings
Christoph

Here is a patch against 2.4.1-pre7 which

2) Again brings the fixes for the accounting. I still think it should be applied.

And of course the prototype should be extern...
