Subject: [PATCH AUTOSEL 5.15 10/28] fs/ntfs3: Avoid possible memory leak
Date: Sun, 29 Oct 2023 18:58:45 -0400 [thread overview]
Message-ID: <20231029225916.791798-10-sashal@kernel.org> (raw)
In-Reply-To: <20231029225916.791798-1-sashal@kernel.org>
From: Su Hui <suhui@nfschina.com>
[ Upstream commit e4494770a5cad3c9d1d2a65ed15d07656c0d9b82 ]
smatch warn:
fs/ntfs3/fslog.c:2172 last_log_lsn() warn: possible memory leak of 'page_bufs'
Jump to label 'out' to free 'page_bufs' and is more consistent with
other code.
