This patch introduces f2fs_cache_node_page(), in this function, page which is
readed ahead will be copy to node_inode's mapping cache.
It will avoid rereading these node pages.
change log:
o check validity of grabbed page suggested by Jaegeuk Kim.

What I meant for the validity was to check the block address to figure
out this node page is up-to-date or not.
IOW, something like this.
get_node_info(sbi, nid, &ni);
if (ni.blk_addr != current block address))
goto out;
npage = grab_cache_page(mapping, nid);
if (unlikely(!npage))
return;
if (unlikely(PageUptodate(npage))) {
f2fs_put_page(npage, 1);
return;
}
memcpy(page_address(npage), page_address(page), PAGE_CACHE_SIZE);
SetPageUptodate(npage);
f2fs_put_page(npage, 1);
out:
return;

Yes, you're right.
