Subject: [PATCH 03/12] cifs: Optimize CIFSFindFirst() response when not searching
Date: Tue, 31 Dec 2024 23:36:33 +0100 [thread overview]
Message-ID: <20241231223642.15722-3-pali@kernel.org> (raw)
In-Reply-To: <20241231223642.15722-1-pali@kernel.org>
When not searching for child entries with msearch wildcard pattern then ask
server just for one output entry. There is no need to ask for more entries
as we are interested only for one search result, as we are doing query on
path.
