Its filename was mm-madvise-clean-up-force_shm_swapin_readahead.patch This patch was dropped because it was merged into the mm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Hugh Dickins Subject: mm/madvise: clean up force_shm_swapin_readahead() Date: Thu, 8 Jun 2023 18:35:14 -0700 (PDT) Some nearby MADV_WILLNEED cleanup unrelated to pte_offset_map_lock(). shmem_swapin_range() is a better name than force_shm_swapin_readahead(). Fix unimportant off-by-one on end_index. Call the swp_entry_t "entry" rather than "swap": either is okay, but entry is the name used elsewhere in mm/madvise.c. Do not assume GFP_HIGHUSER_MOVABLE: that's right for anon swap, but shmem should take gfp from mapping. Pass the actual vma and address to read_swap_cache_async(), in case a NUMA mempolicy applies. lru_add_drain() at outer level, like madvise_willneed()'s other branch.
