[PATCHv4 13/24] mm, vmstats: new THP splitting event

2015-03-04 Thread Kirill A. Shutemov
The patch replaces THP_SPLIT with tree events: THP_SPLIT_PAGE, THP_SPLIT_PAGE_FAILT and THP_SPLIT_PMD. It reflects the fact that we now can split PMD without the compound page and that split_huge_page() can fail. Signed-off-by: Kirill A. Shutemov --- include/linux/vm_event_item.h | 4 +++- mm/hu
