Subject: [PATCH v2 1/3] mlx5: Use refcount_t for refcount
Date: Sat, 3 Aug 2019 01:23:41 +0800 [thread overview]
Message-ID: <20190802172341.8359-1-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.
