From 327dafb1c61c9da7b95ac6cc7634a2340cc9509c Mon Sep 17 00:00:00 2001 From: Arthur Jones Date: Fri, 25 Jul 2008 01:49:10 -0700 Subject: edac: core fix redundant sysfs controls to parameters /sys/devices/system/edac/mc has a few files which are duplicated in /sys/module/edac_core/parameters. Now that all the functionality is duplicated between these two locations, we remove the former kobject attributes and update the documentation.
