The patch titled mm: shmem: change remove_from_page_cache has been removed from the -mm tree. Its filename was mm-shmem-change-remove_from_page_cache.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: mm: shmem: change remove_from_page_cache From: Minchan Kim <minchan.kim@xxxxxxxxx> This patch series changes remove_from_page_cache()'s page ref counting rule. Page cache ref count is decreased in delete_from_page_cache(). So we don't need to decrease the page reference in callers.
