Hello Amir,

I have already backported+verified the fix to v4.13 in one of our internal
trees.

Like you said, I simply dropped the last hunk of the patch that modfied
inode.c, i.e. I simply ignored this hunk of the patch:

@@ -685,7 +702,7 @@ struct inode *ovl_get_inode(struct dentry *dentry, struct dentry *upperdentry,
 		ovl_set_flag(OVL_IMPURE, inode);
 
 	/* Check for non-merge dir that may have whiteouts */
-	if (S_ISDIR(realinode->i_mode)) {
+	if (is_dir) {
 		struct ovl_entry *oe = dentry->d_fsdata;
 
 		if (((upperdentry && lowerdentry) || oe->numlower > 1) ||

Niklas
