This patch contains the following cleanups:
- every file should include the headers containing the prototypes for
its global functions
- make the needlessly global putback_lru_pages() static

Well we may have to re-rexport putback_lru_pages() again soon because
of the hotplug / memory compaction work but until that time.

Sorry for late response.
But, this patch is the cause of compile error of memory unplug code of
2.6.23-rc1-mm2. It uses putback_lru_pages().
Don't make it static please... :-(
Bye.

Right. But Adrian insisted since it was currently not used upstream.
So I guess you will have to revert this piece in your unplug code.

Okay, I'll take are.
But I'm too busy in these days.
Andrew, If you have to drop unplug patch set, please do.
I'll rework all when I find time.
Thanks,
