The following patch is the same I already submitted months ago!
It makes it feasible to compile the kernel without support for
networking.
Alan Cox promised that there will be some better cleaner ... solution.
It didn't appear. And since we are going to stabilize the kernel again
this should
be applied. Toght even if the CONFIG_UNIX is a compleate missnomer.
If you are not connected this patch will you save some several 100k's in
kernel size.
(Yes the current TCP/IP networking code is HUGE).
If there are doubt's about why I did rearrange the compilation of some
otherwise not used
stuff please just think about the following scenario:
There are the modules A.o B.o and C.o. Let C.o be the main modules (in
esp. containing the main entry point.)
C.o doesn't use anything from A.o and anything from B.o but A.o contains
refferences to
symbols defined in B.o and B.o contains refferences to symbols defined
in A.o.
What do You think ld does with them? It's simple it sees some symbols
from A.o beeing used (used in B.o!) and it sees some symbols from B.o
beeing used (in A.o). Therefore it includes BOTH A.o and B.o into the
produced executable. Despite the fact that both of them are COMPLEATLY
DEAD code. Call it a bug or a feature of the binutils I don't see any
way
to correct this problem in them easly. And I wonder it there are even
more circumstances like that in the kernel.
