There are some refcnt in type of atomic_t in RDMA subsystem, almost all of them is wrote before the refcount_t is acheived in kernel. refcount_t is better than integer for reference counting, it will WARN on overflow/underflow and avoid use-after-free risks. Weihang Li (6): RDMA/core: Use refcount_t instead of atomic_t for reference counting RDMA/hns: Use refcount_t instead of atomic_t for reference counting RDMA/hns: Use refcount_t APIs for HEM RDMA/cxgb4: Use refcount_t instead of atomic_t for reference counting RDMA/i40iw: Use refcount_t instead of atomic_t for reference counting RDMA/ipoib: Use refcount_t instead of atomic_t for reference counting drivers/infiniband/core/iwcm.c | 9 +++-- drivers/infiniband/core/iwcm.h | 2 +- drivers/infiniband/core/iwpm_util.c | 12 ++++--- drivers/infiniband/core/iwpm_util.h | 2 +- drivers/infiniband/core/mad_priv.h | 2 +- drivers/infiniband/core/multicast.c | 30 ++++++++-------- drivers/infiniband/core/uverbs.h | 2 +- drivers/infiniband/core/uverbs_main.c | 12 +++---- drivers/infiniband/hw/cxgb4/cq.c | 6 ++-- drivers/infiniband/hw/cxgb4/ev.c | 8 ++--- drivers/infiniband/hw/cxgb4/iw_cxgb4.h | 2 +- drivers/infiniband/hw/hns/hns_roce_cq.c | 8 ++--- drivers/infiniband/hw/hns/hns_roce_device.h | 6 ++-- drivers/infiniband/hw/hns/hns_roce_hem.c | 33 +++++++++--------- drivers/infiniband/hw/hns/hns_roce_hem.h | 4 +-- drivers/infiniband/hw/hns/hns_roce_qp.c | 12 +++---- drivers/infiniband/hw/hns/hns_roce_srq.c | 8 ++--- drivers/infiniband/hw/i40iw/i40iw.h | 2 +- drivers/infiniband/hw/i40iw/i40iw_cm.c | 54 ++++++++++++++--------------- drivers/infiniband/hw/i40iw/i40iw_cm.h | 4 +-- drivers/infiniband/hw/i40iw/i40iw_main.c | 2 +- drivers/infiniband/hw/i40iw/i40iw_puda.h | 2 +- drivers/infiniband/hw/i40iw/i40iw_utils.c | 10 +++--- drivers/infiniband/ulp/ipoib/ipoib.h | 4 +-- drivers/infiniband/ulp/ipoib/ipoib_main.c | 8 ++--- 25 files changed, 123 insertions(+), 121 deletions(-) -- 2.7.4
