I have just created since-3.19 branch in mm git tree (http://git.kernel.org/?p=linux/kernel/git/mhocko/mm.git;a=summary). It is based on v3.19 tag in Linus tree and mmotm-2015-02-25-21-19. I have pulled some cgroup wide changes from Tejun. As usual mmotm trees are tagged with signed tag (finger print BB43 1E25 7FB8 660F F2F1 D22D 48E2 09A2 B310 E347) The current shortlog says: Alexander Kuleshov (1): fs: proc: use PDE() to get proc_dir_entry Andrea Arcangeli (6): mm: gup: add get_user_pages_locked and get_user_pages_unlocked mm: gup: add __get_user_pages_unlocked to customize gup_flags mm: gup: use get_user_pages_unlocked within get_user_pages_fast mm: gup: use get_user_pages_unlocked mm: gup: kvm use get_user_pages_unlocked mm: incorporate zero pages into transparent huge pages fix Andrew Morton (9): mm/vmstat.c: fix/cleanup ifdefs mm/page_alloc.c:__alloc_pages_nodemask(): don't alter arg gfp_mask mm-cma-release-trigger-checkpatch-fixes mm-cma-allocation-trigger-fix mm-compaction-enhance-compaction-finish-condition-fix page_writeback-cleanup-mess-around-cancel_dirty_page-checkpatch-fixes mm-hide-per-cpu-lists-in-output-of-show_mem-fix x86-add-pmd_-for-thp-fix sparc-add-pmd_-for-thp-fix Andrey Ryabinin (2): mm, hugetlb: remove unnecessary lower bound on sysctl handlers"? mm: hugetlb: fix type of hugetlb_treat_as_movable variable Andrey Skvortsov (1): gitignore: ignore tar-install build directory Andy Lutomirski (1): all arches, signal: move restart_block to struct task_struct Andy Shevchenko (1): fs/proc/array.c: convert to use string_escape_str() Aneesh Kumar K.V (1): mm/thp: allocate transparent hugepages on local node Baoquan He (2): mm: fix typo of MIGRATE_RESERVE in comment mm/memblock.c: rename local variable of memblock_type to `type' Christoph Hellwig (1): fs: export inode_to_bdi and use it in favor of mapping->backing_dev_info Christoph Lameter (1): vmstat: Reduce time interval to stat update on idle cpu Cyril Bur (2): kernel/sched/clock.c: add another clock for use with the soft lockup watchdog powerpc: add running_clock for powerpc to prevent spurious softlockup warnings Cyrill Gorcunov (1): Documentation/filesystems/proc.txt: describe /proc/<pid>/map_files David Rientjes (1): mm, hotplug: fix concurrent memory hot-add deadlock Ebru Akagunduz (2): mm: incorporate read-only pages into transparent huge pages mm: incorporate zero pages into transparent huge pages Ganesh Mahendran (3): zram: free meta table in zram_meta_free mm/zpool: add name argument to create zpool mm/zsmalloc: add statistics support Geert Uytterhoeven (1): linux/types.h: Always use unsigned long for pgoff_t George G.
