Subject: [PATCH 5/5] cachefiles: correct the return value of cachefiles_check_auxdata()
Date: Wed, 24 Apr 2024 11:27:32 +0800 [thread overview]
Message-ID: <20240424032732.2711487-6-libaokun@huaweicloud.com> (raw)

From: Baokun Li <libaokun1@huawei.com>
Pass the error code to ret when xlen < 0 to avoid misleading the caller.
