Subject: [PATCH -next 3/3] fail_function: fix wrong use of fei_attr_remove()
Date: Fri, 26 Aug 2022 15:33:37 +0800 [thread overview]
Message-ID: <20220826073337.2085798-3-yangyingliang@huawei.com> (raw)
In-Reply-To: <20220826073337.2085798-1-yangyingliang@huawei.com>
If register_kprobe() fails, the new attr is not added to the list yet,
so it should call fei_attr_free() intstead.
Fixes: 4b1a29a7f542 ("error-injection: Support fault injection framework")
