Hi Chao,
It seems that we already have a readahed function for node pages,
ra_node_page().
So, we don't make a page list for this, but can use the node_inode's
page cache.
So how about writing ra_node_pages() which use the node_inode's page
cache?
Thanks,

If cp has no CP_UMOUNT_FLAG, we will read all pages in whole node segment
one by one, it makes low performance. So let's merge contiguous pages and
readahead for better performance.
