The patch titled mmap-avoid-unnecessary-anon_vma-lock-acquisition-in-vma_adjust-tweak has been removed from the -mm tree. Its filename was mmap-avoid-unnecessary-anon_vma-lock-acquisition-in-vma_adjust-tweak.patch This patch was dropped because it was folded into mmap-avoid-unnecessary-anon_vma-lock-acquisition-in-vma_adjust.patch The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: mmap-avoid-unnecessary-anon_vma-lock-acquisition-in-vma_adjust-tweak From: Hugh Dickins <hugh.dickins@xxxxxxxxxxxxx> Cc: Lee Schermerhorn <lee.schermerhorn@xxxxxx> Signed-off-by: Hugh Dickins <hugh.dickins@xxxxxxxxxxxxx> Cc: Nick Piggin <npiggin@xxxxxxx> Cc: Eric Whitney <eric.whitney@xxxxxx> Signed-off-by: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx> --- mm/mmap.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff -puN mm/mmap.c~mmap-avoid-unnecessary-anon_vma-lock-acquisition-in-vma_adjust-tweak mm/mmap.c --- a/mm/mmap.c~mmap-avoid-unnecessary-anon_vma-lock-acquisition-in-vma_adjust-tweak +++ a/mm/mmap.c @@ -573,7 +573,7 @@ again: remove_next = 1 + (end > next-> * When changing only vma->vm_end, we don't really need * anon_vma lock. */ - if ((file || insert || importer) && vma->anon_vma) + if (vma->anon_vma && (insert || importer || start != vma->vm_start)) anon_vma = vma->anon_vma; if (anon_vma) { spin_lock(&anon_vma->lock); _ Patches currently in -mm which might be from hugh.dickins@xxxxxxxxxxxxx are origin.patch mm-oom-analysis-add-shmem-vmstat.patch mm-vmstat-add-isolate-pages.patch ksm-add-mmu_notifier-set_pte_at_notify.patch ksm-first-tidy-up-madvise_vma.patch ksm-define-madv_mergeable-and-madv_unmergeable.patch ksm-the-mm-interface-to-ksm.patch ksm-no-debug-in-page_dup_rmap.patch ksm-identify-pageksm-pages.patch ksm-kernel-samepage-merging.patch ksm-prevent-mremap-move-poisoning.patch ksm-change-copyright-message.patch ksm-change-ksm-nice-level-to-be-5.patch ksm-rename-kernel_pages_allocated.patch ksm-move-pages_sharing-updates.patch ksm-pages_unshared-and-pages_volatile.patch ksm-break-cow-once-unshared.patch ksm-keep-quiet-while-list-empty.patch ksm-five-little-cleanups.patch ksm-fix-endless-loop-on-oom.patch ksm-distribute-remove_mm_from_lists.patch ksm-fix-oom-deadlock.patch ksm-fix-deadlock-with-munlock-in-exit_mmap.patch ksm-sysfs-and-defaults.patch ksm-add-some-documentation.patch ksm-remove-vm_mergeable_flags.patch ksm-clean-up-obsolete-references.patch ksm-unmerge-is-an-origin-of-ooms.patch ksm-mremap-use-err-from-ksm_madvise.patch mm-add_to_swap_cache-must-not-sleep.patch mm-add_to_swap_cache-does-not-return-eexist.patch mm-includecheck-fix-for-mm-shmemc.patch mm-introduce-page_lru_base_type.patch mm-replace-various-uses-of-num_physpages-by-totalram_pages.patch mm-munlock-use-follow_page.patch mm-remove-unused-gup-flags.patch mm-add-get_dump_page.patch mm-foll_dump-replace-foll_anon.patch mm-follow_hugetlb_page-flags.patch mm-fix-anonymous-dirtying.patch mm-reinstate-zero_page.patch mm-foll-flags-for-gup-flags.patch mm-munlock-avoid-zero_page.patch mm-hugetlbfs_pagecache_present.patch mm-zero_page-without-pte_special.patch mm-move-highest_memmap_pfn.patch mmap-remove-unnecessary-code.patch tmpfs-depend-on-shmem.patch mmap-avoid-unnecessary-anon_vma-lock-acquisition-in-vma_adjust.patch mmap-avoid-unnecessary-anon_vma-lock-acquisition-in-vma_adjust-tweak.patch mmap-save-some-cycles-for-the-shared-anonymous-mapping.patch hugetlbfs-allow-the-creation-of-files-suitable-for-map_private-on-the-vfs-internal-mount.patch mm-add-map_hugetlb-for-mmaping-pseudo-anonymous-huge-page-regions.patch hugetlb-add-map_hugetlb-for-mmaping-pseudo-anonymous-huge-page-regions.patch hugetlb-add-map_hugetlb-for-mmaping-pseudo-anonymous-huge-page-regions-fix.patch hugetlb-add-map_hugetlb-example.patch shmem-initialize-struct-shmem_sb_info-to-zero.patch getrusage-fill-ru_maxrss-value.patch getrusage-fill-ru_maxrss-value-update.patch walk-system-ram-range-fix.patch ramfs-move-ramfs_magic-to-include-linux-magich.patch memory-controller-soft-limit-organize-cgroups-v9-fix.patch prio_tree-debugging-patch.patch -- To unsubscribe from this list: send the line "unsubscribe mm-commits" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
