From 14e98c5ca8bed825f65cbf11cb0ffd2c09dac2f4 Mon Sep 17 00:00:00 2001 From: Chandra Seetharaman Date: Thu, 13 Nov 2008 23:39:06 +0000 Subject: [PATCH] dm mpath: warn if args ignored Currently dm ignores the parameters provided to hardware handlers without providing any notifications to the user. This patch just prints a warning message so that the user knows that the arguments are ignored.
