From 08d8f8a5b094b66b29936e8751b4a818b8db1207 Mon Sep 17 00:00:00 2001 From: Vivek Goyal Date: Mon, 27 Nov 2017 10:12:44 -0500 Subject: ovl: Pass ovl_get_nlink() parameters in right order Right now we seem to be passing index as "lowerdentry" and origin.dentry as "upperdentry". IIUC, we should pass these parameters in reversed order and this looks like a bug.
