Subject: [PATCH 1/3] mlx5: Use refcount_t for refcount
Date: Fri, 2 Aug 2019 20:10:44 +0800 [thread overview]
Message-ID: <20190802121044.1375-1-hslester96@gmail.com> (raw)
refcount_t is better for reference counters since its
implementation can prevent overflows.
So convert atomic_t ref counters to refcount_t.
