Subject: [PATCH AUTOSEL 5.4 14/18] samples/bpf: Fix fout leak in hbm's run_bpf_prog
Date: Thu, 4 May 2023 15:50:36 -0400 [thread overview]
Message-ID: <20230504195042.3808716-14-sashal@kernel.org> (raw)
In-Reply-To: <20230504195042.3808716-1-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.
