From bd6c57dda666868abb222c1fa48e72f81db20e70 Mon Sep 17 00:00:00 2001 From: Jeff Mahoney Date: Fri, 10 Jun 2016 17:03:59 -0400 Subject: [PATCH] btrfs: simpilify btrfs_subvol_inherit_props We just need a superblock, but we look it up using two different roots depending on the call site. Let's just use a superblock pointer initialized at the outset. This is mostly for Coccinelle not to choke on my root push up set.
