Subject: [PATCH v3 for-next 03/13] RDMA/core: Use refcount_t instead of atomic_t on refcount of ib_mad_snoop_private
Date: Tue, 25 May 2021 14:51:34 +0800 [thread overview]
Message-ID: <1621925504-33019-4-git-send-email-liweihang@huawei.com> (raw)
In-Reply-To: <1621925504-33019-1-git-send-email-liweihang@huawei.com>
The refcount_t API will WARN on underflow and overflow of a reference
counter, and avoid use-after-free risks.
