From cdb345a877205849042a18cc568a17620935b8f9 Mon Sep 17 00:00:00 2001 From: Lu Fengqi Date: Tue, 29 May 2018 15:01:53 +0800 Subject: btrfs: Remove fs_info argument from btrfs_uuid_tree_add This function always takes a transaction handle which contains a reference to the fs_info. Use that and remove the extra argument.
