Revision 0dcc48c15f63ee86c2fcd33968b08d651f0360a5 authored by KAMEZAWA Hiroyuki on 09 September 2010, 23:38:01 UTC, committed by Linus Torvalds on 10 September 2010, 01:57:24 UTC
next_active_pageblock() is for finding next _used_ freeblock. It skips several blocks when it finds there are a chunk of free pages lager than pageblock. But it has 2 bugs. 1. We have no lock. page_order(page) - pageblock_order can be minus. 2. pageblocks_stride += is wrong. it should skip page_order(p) of pages.
