[PATCH] 2.5.21 inline abuse...

[Martin Dalecki <dalecki@evision-ventures.com>]

[-- Attachment #1: Type: text/plain, Size: 924 bytes --]

The attached patch is trying to address the most obvious
abuses or inadequacies in the usage of the inline attribute
to functions. Many of the remaining usages should be removed
as well since apparently GCC got really good at figuring out
on its own whatever it makes sense to inline a function or not.

Since the patch isn't very big I didn't bother to split
it up in to a series of "micropatches".
However if you "insist" I could provide this.

And well here are the "before/after" diet images:


wto cze 11 10:56:03 CEST 2002

Size before:

[root@kozaczek linux]# size vmlinux
    text    data     bss     dec     hex filename
1482859  249992  255852 1988703  1e585f vmlinux

    text    data     bss     dec     hex filename
1476379  249992  255852 1982223  1e3f0f vmlinux

No question it's worth it. The above numbers should
be higher with older GCC version, which where not that
eager to inline functions on they own.
