Merge branch 'akpm' (patches from Andrew)
Merge misc updates from Andrew Morton: "A few small subsystems and some of MM. 172 patches. Subsystems affected by this patch series: hexagon, scripts, ntfs, ocfs2, vfs, and mm (slab-generic, slab, slub, debug, pagecache, swap, memcg, pagemap, mprotect, mremap, page-reporting, vmalloc, kasan, pagealloc, memory-failure, hugetlb, vmscan, z3fold, compaction, mempolicy, oom-kill, hugetlbfs, and migration)" * emailed patches from Andrew Morton <akpm@linux-foundation.org>: (172 commits) mm/migrate: remove unneeded semicolons hugetlbfs: remove unneeded return value of hugetlb_vmtruncate() hugetlbfs: fix some comment typos hugetlbfs: correct some obsolete comments about inode i_mutex hugetlbfs: make hugepage size conversion more readable hugetlbfs: remove meaningless variable avoid_reserve hugetlbfs: correct obsolete function name in hugetlbfs_read_iter() hugetlbfs: use helper macro default_hstate in init_hugetlbfs_fs hugetlbfs: remove useless BUG_ON(!inode) in hugetlbfs_setattr() hugetlbfs: remove special hugetlbfs_set_page_dirty() mm/hugetlb: change hugetlb_reserve_pages() to type bool mm, oom: fix a comment in dump_task() mm/mempolicy: use helper range_in_vma() in queue_pages_test_walk() numa balancing: migrate on fault among multiple bound nodes mm, compaction: make fast_isolate_freepages() stay within zone mm/compaction: fix misbehaviors of fast_find_migrateblock() mm/compaction: correct deferral logic for proactive compaction mm/compaction: remove duplicated VM_BUG_ON_PAGE !PageLocked mm/compaction: remove rcu_read_lock during page compaction z3fold: simplify the zhdr initialization code in init_z3fold_page() ...
