Date: Wed, 21 Oct 2020 19:19:23 +0800 [thread overview]
Message-ID: <0c755de289f228e67897818639a171cbf1d768ae.1603207676.git.wangyunjian@huawei.com> (raw)
In-Reply-To: <cover.1603207676.git.wangyunjian@huawei.com>

Fix return value, using -EAGAIN instead of 0 when the callback is busy
and using -ENOENT instead of 0 when the callback is not found.
