Hi,
By dumping the mem_map, I've observed some werid pages. Let me know
if you've seen this before or have a hunch about it.
Basically, I've seen many of pages with page->count == 1 and page->flags
= 0x1000000. I'm using kernel 2.4.18-3 w/ rmap and w/HIGHMEM disabled.
The machine only has one entry on the pgdat_list (that's why the 1 in
0x1000000). But I can decipher what can cause a page to be allocated with
an empty page->flag. Any clues?
