From 0e0b2afdf644aa523f5eb10ce1f9e3c6cd8362ec Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Wed, 10 Aug 2016 11:23:43 -0400 Subject: [PATCH] kernfs: add dummy implementation of kernfs_path_from_node() The dummy version of kernfs_path_from_node() was missing. This currently doesn't break anything. Let's add it for consistency and to ease adding wrappers around it. v2: Removed stray ';' which was causing build failures.
