From e2f238f7d5a1fa69ff1884d37acf9a2a3a01b308 Mon Sep 17 00:00:00 2001 From: Honggang Li Date: Mon, 4 Nov 2019 20:43:22 +0800 Subject: configfs: calculate the depth of parent item When create symbolic link, create_link should calculate the depth of the parent item. However, both the first and second parameters of configfs_get_target_path had been set to the target. Broken symbolic link created. $ targetcli ls / o- / ............................................................. [...] o- backstores ..................................................
