This is a compromize for the systems that are critical on performance and cannot accept even slight delay on the refcounter operations. Elena Reshetova (5): mm: convert bdi_writeback_congested.refcnt from atomic_t to refcount_t mm: convert anon_vma.refcount from atomic_t to refcount_t mm: convert kmemleak_object.use_count from atomic_t to refcount_t mm: convert mm_struct.mm_users from atomic_t to refcount_t mm: convert mm_struct.mm_count from atomic_t to refcount_t arch/alpha/kernel/smp.c | 6 +++--- arch/arc/mm/tlb.c | 2 +- arch/blackfin/mach-common/smp.c | 4 ++-- arch/ia64/include/asm/tlbflush.h | 2 +- arch/ia64/kernel/smp.c | 2 +- arch/ia64/sn/kernel/sn2/sn2_smp.c | 4 ++-- arch/mips/kernel/process.c | 2 +- arch/mips/kernel/smp.c | 6 +++--- arch/parisc/include/asm/mmu_context.h | 2 +- arch/powerpc/mm/hugetlbpage.c | 2 +- arch/powerpc/mm/icswx.c | 4 ++-- arch/sh/kernel/smp.c | 6 +++--- arch/sparc/kernel/smp_64.c | 6 +++--- arch/sparc/mm/srmmu.c | 2 +- arch/um/kernel/tlb.c | 2 +- arch/x86/kernel/tboot.c | 4 ++-- drivers/firmware/efi/arm-runtime.c | 4 ++-- drivers/gpu/drm/amd/amdkfd/kfd_process.c | 2 +- fs/coredump.c | 2 +- fs/proc/base.c | 2 +- fs/proc/task_nommu.c | 4 ++-- fs/userfaultfd.c | 3 +-- include/linux/backing-dev-defs.h | 3 ++- include/linux/backing-dev.h | 4 ++-- include/linux/mm_types.h | 5 +++-- include/linux/rmap.h | 7 ++++--- include/linux/sched/mm.h | 10 +++++----- kernel/events/uprobes.c | 2 +- kernel/exit.c | 2 +- kernel/fork.c | 12 ++++++------ kernel/sched/core.c | 2 +- lib/is_single_threaded.c | 2 +- mm/backing-dev.c | 13 +++++++------ mm/debug.c | 4 ++-- mm/init-mm.c | 4 ++-- mm/khugepaged.c | 2 +- mm/kmemleak.c | 16 ++++++++-------- mm/ksm.c | 2 +- mm/memory.c | 2 +- mm/mmu_notifier.c | 10 +++++----- mm/mprotect.c | 2 +- mm/oom_kill.c | 2 +- mm/rmap.c | 14 +++++++------- mm/swapfile.c | 2 +- mm/vmacache.c | 2 +- 45 files changed, 100 insertions(+), 97 deletions(-) -- 2.7.4
