Subject: [PATCH 2/4] mm/swapfile.c: tmp is always smaller than max
Date: Sun, 19 Apr 2020 01:39:19 +0000 [thread overview]
Message-ID: <20200419013921.14390-2-richard.weiyang@gmail.com> (raw)
In-Reply-To: <20200419013921.14390-1-richard.weiyang@gmail.com>
If tmp is bigger or equal to max, we would jump to new_cluster.
Return true directly.
