The patch titled Subject: mm/swap_state.c: use the same way to count page in [add_to|delete_from]_swap_cache has been removed from the -mm tree. Its filename was mm-swap_statec-use-the-same-way-to-count-page-in-_swap_cache.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Wei Yang <richard.weiyang@xxxxxxxxx> Subject: mm/swap_state.c: use the same way to count page in [add_to|delete_from]_swap_cache add_to_swap_cache() and delete_from_swap_cache() are counterparts, while currently they use different ways to count pages. It doesn't break anything because we only have two sizes for PageAnon, but this is confusing and not good practice. This patch corrects it by making both functions use hpage_nr_pages().
