Subject: [PATCH AUTOSEL 6.6 15/61] samples/bpf: Fix a resource leak
Date: Sun, 24 Nov 2024 08:44:50 -0500	[thread overview]
Message-ID: <20241124134637.3346391-15-sashal@kernel.org> (raw)
In-Reply-To: <20241124134637.3346391-1-sashal@kernel.org>

From: Zhu Jun <zhujun2@cmss.chinamobile.com>

[ Upstream commit f3ef53174b23246fe9bc2bbc2542f3a3856fa1e2 ]

The opened file should be closed in show_sockopts(), otherwise resource
leak will occur that this problem was discovered by reading code
