From b62a206bfbf3e9c52abc28253bf3baedc8d99880 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Pali=20Roh=C3=A1r?= Date: Mon, 30 Dec 2024 20:55:53 +0100 Subject: [PATCH] cifs: Optimize CIFSFindFirst() response when not searching MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit 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. CIFSFindFirst() with msearch=false is called by the cifs_query_path_info() function.
