From 852b6ed110990891d21bf76b4f46a3c854866f67 Mon Sep 17 00:00:00 2001 From: Nicholas Bellinger Date: Wed, 22 Aug 2012 18:45:11 -0700 Subject: [PATCH] target/iblock: Use match_strlcpy for Opt_udev_path string assignment Following commit dbc6e0222 from Al Viro for fileio, go ahead and make Opt_udev_path within iblock_set_configfs_dev_params use match_strlcpy instead of the match_strdup -> snprintf -> kfree equivalent.
