PATCH 1/1 mm/vmscan.c: 'lru' may be used without initialized after the patch "3abf380..." in next-20130607 tree
'lru' may be used without initialized, so need regressing part of the related patch.

That looks right. Why the heck didn't gcc-4.4.4 (at least) warn about it?

Sorry I don't know either, I find it by reading code, this time.
It is really necessary to continue analyzing why. In 2nd half of 2013, I have planned to make some patches outside kernel but related with kernel (e.g. LTP, gcc patches).
This kind of issue is a good chance for me to start in 2nd half of 2013 (start from next month).
So if no others reply for it, I will start analyzing it in the next month, and plan to finish within a month (before 2013-07-31).
Welcome additional suggestions or completions.
Thanks.

Under gcc 4.7.2 20120921 (Red Hat 4.7.2-2) also cause this issue.
The root cause is:
for putback_lur_page() in mm/vmscan.c for next-20130621 tree.
the compiler assumes "lru == LRU_UNEVICTABLE" instead of report warnings (uninitializing lru)
The details are below, and the related info and warn are in attachments, please check, thanks.
Next, I will compile gcc compiler with the gcc latest code, if also has this issue, I should communicate with gcc mailing list for it.
Thanks.

It is really necessary to continue analyzing why. In 2nd half of 2013, I have planned to make some patches outside kernel but related with kernel (e.g. LTP, gcc patches).

Under the gcc which from the source code in svn. it still has this issue. I should communicate with gcc mailing list (or their bugzilla) for it.

'lru' may be used without initialized, so need regressing part of the related patch.

Thanks for catching this but I have one question. Why are you clearing the active bit?
Before 3abf380 we did
active = TestClearPageActive(page);
lru = active + page_lru_base_type(page);lru_cache_add_lru(page, lru);
so if the page was active before then it gets added to the active list. When 3abf380 is applied. it becomes.
Leave PageActive alonelru_cache_add(page);
..... until __pagevec_lru_add -> __pagevec_lru_add_fn int file = page_is_file_cache(page);
int active = PageActive(page);
enum lru_list lru = page_lru(page);
After your patch it's
Clear PageActivelru_cache_add(page)
.......
always add to inactive list
I do not think you intended to do this and if you did, it deserves far more comment than being a compile warning fix. In putback_lru_page we only care about whether the lru was unevictable or not. Hence I think what you meant to do was simply
lru = page_lru_base_type(page);
If you agree then can you resend a revised version to Andrew please?

Oh, it is my fault, I only want to regress part of the original patch, did not notice clearing the active bit.

Yes, I should do, but excuse me, I do not quite know about 'revised version'.
I guess it means I need still send the related patch which base on the original one, e.g. for next-20130618:
