From 6bccf3ab1e1f0913268bfcd1c09cadb1f4f2857d Mon Sep 17 00:00:00 2001 From: Jeff Mahoney Date: Tue, 21 Jun 2016 21:16:51 -0400 Subject: btrfs: call functions that always use the same root with fs_info instead There are many functions that are always called with the same root argument. Rather than passing the same root every time, we can pass an fs_info pointer instead and have the function get the root pointer itself.
