[RFC PATCH 00/10] Reduce stack usage used by page reclaim V1
This is just an RFC to reduce some of the more obvious stack usage in page reclaim. It's a bit rushed and I haven't tested this yet but am sending it out as there may be others working on similar material and would rather avoid overlap. I built on some of Kosaki Motohiro's work. On X86 bit, stack usage figures (g... 15 Apr 2010 13:38

[PATCH 04/10] vmscan: Remove useless loop at end of do_try_to_free_pages

[PATCH 09/10] vmscan: Setup pagevec as late as possible in shrink_page_list()
shrink_page_list() sets up a pagevec to release pages as according as they are free. It uses significant amounts of stack on the pagevec. This patch adds pages to be freed via pagevec to a linked list which is then freed en-masse at the end. This avoids using stack in the main path that potentially calls writepage(... 15 Apr 2010 13:38

[PATCH 06/10] vmscan: Split shrink_zone to reduce stack usage
shrink_zone() calculculates how many pages it needs to shrink from each LRU list in a given pass. It uses a number of temporary variables to work this out that then remain on the stack. This patch splits the function so that some of the stack variables can be discarded. Signed-off-by: Mel Gorman <mel(a)csn.ul.ie> ... 15 Apr 2010 13:38
