Summaries: 01 - removes the use of zone_end_pfn as a local var name. 02 - adds zone_end_pfn(), zone_is_initialized(), zone_is_empty() and zone_spans_pfn() 03 - adds a VM_BUG using zone_is_initialized() in __free_one_page()
04 - add ensure_zone_is_initialized() (for memory_hotplug) 05 - use the above addition. 06 - add pgdat_end_pfn() and pgdat_is_empty() 07,08,09,10,11,12,16,17 - use the new helpers 13 - avoid repeating checks for section in page flags by adding a define. 14 - memory hotplug: factor out zone+pgdat growth. 15 - add debugging message to VM_BUG check. As a general concern: spanned_pages & start_pfn (in pgdat & zone) are supposed to be locked (via a seqlock) when read (due to changes to them via memory_hotplug), but very few (only 1?) of their users appear to actually lock them. -- include/linux/mm.h | 8 ++++-- include/linux/mmzone.h | 34 ++++++++++++++++++++++--- mm/compaction.c | 10 ++++---- mm/kmemleak.c | 5 ++-- mm/memory_hotplug.c | 68 ++++++++++++++++++++++++++++---------------------- mm/page_alloc.c | 31 +++++++++++++---------- mm/vmstat.c | 2 +- 7 files changed, 100 insertions(+), 58 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
