I intentional left this code as is so that the driver will still works with older version of the EDAC code. Since you don't want this, I will get rip of this. > > xgene_edac_l3_create_debugfs_nodes() does call debugfs_create_dir() > creating a top-level edac debugfs node too. Why? Each subnode will create an folder under the edac debug fs. It is no different than the EDAC MC debug file system. You will see: /sys/kernel/debug/edac/mc0, .. /sys/kernel/debug/edac/mc2 /sys/kernel/debug/edac/pmd0, ... /sys/kernel/debug/edac/pmd3 /sys/kernel/debug/edac/l3c4 > > Please go through the previous comments I had and make sure you've > incorporated them all. I'm not wasting time reviewing half-baked stuff.

Which looks like >you could use it. [Loc Ho] I had already reversed the logic for the L3 and SoC. Are you asking for the MC/PMD (earlier posting)? The MC/PMD routine isn't that big.
