Subject: [PATCH v3 for-next 00/13] RDMA: Use refcount_t for reference counting
Date: Tue, 25 May 2021 14:51:31 +0800 [thread overview]
Message-ID: <1621925504-33019-1-git-send-email-liweihang@huawei.com> (raw)
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.
Changes since v2:
* Drop i40iw related parts because this driver will be removed soon.
* Link: https://patchwork.kernel.org/project/linux-rdma/cover/1621590825-60693-1-git-send-email-liweihang@huawei.com/
Changes since v1:
* Split these patches by variable granularity.
* Fix a warning on refcount of struct mcast_group.
* Add a patch on rdmavt.
* Drop "RDMA/hns: Use refcount_t APIs for HEM".
* Link: https://patchwork.kernel.org/project/linux-rdma/cover/1620958299-4869-1-git-send-email-liweihang@huawei.com/
