Subject: [RFC PATCH v3 7/9] kernfs: Adjust argument for lookup_positive_unlocked()
Date: Fri, 15 May 2020 15:20:45 +0800	[thread overview]
Message-ID: <20200515072047.31454-8-cgxu519@mykernel.net> (raw)
In-Reply-To: <20200515072047.31454-1-cgxu519@mykernel.net>

Set 0 as lookup flag argument when calling lookup_positive_unlocked(),
because we don't hope to drop negative dentry in lookup.
