In particular, my laptop will now successfully resume from suspend to disk, which always failed without the patches. From Jiang Liu: 1. [RFT PATCH v2 1/5] mm: introduce new field "managed_pages" to struct zone 2. [RFT PATCH v1 2/5] mm: replace zone->present_pages with zone->managed_pages if appreciated 3. [RFT PATCH v1 3/5] mm: set zone->present_pages to number of existing pages in the zone 4. [RFT PATCH v2 4/5] mm: provide more accurate estimation of pages occupied by memmap 5. [RFT PATCH v1 5/5] mm: increase totalram_pages when free pages allocated by bootmem allocator From Andrew Morton: 6. mm-provide-more-accurate-estimation-of-pages-occupied-by-memmap.patch Tested-by: Chris Clayton > Thanks, > Chris > >
