Subject: [PATCH AUTOSEL 5.10 16/24] samples/bpf: Fix fout leak in hbm's run_bpf_prog
Date: Thu, 4 May 2023 15:49:29 -0400 [thread overview]
Message-ID: <20230504194937.3808414-16-sashal@kernel.org> (raw)
In-Reply-To: <20230504194937.3808414-1-sashal@kernel.org>
From: Hao Zeng <zenghao@kylinos.cn>
[ Upstream commit 23acb14af1914010dd0aae1bbb7fab28bf518b8e ]
Fix fout being fopen'ed but then not subsequently fclose'd. In the affected
branch, fout is otherwise going out of scope.
