From 195291e68c2ad59a046fc56d32bf59635b100e5c Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Wed, 9 Feb 2011 12:01:42 -0500 Subject: [PATCH] cifs: clean up checks in cifs_echo_request Follow-on patch to 7e90d705 which is already in Steve's tree... The check for tcpStatus == CifsGood is not meaningful since it doesn't indicate whether the NEGOTIATE request has been done. Also, clarify why we're checking for maxBuf == 0.
