From dfe8aec4520bff8e69c8704421ef7f47c65ca778 Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Fri, 5 Nov 2021 16:45:36 -0400 Subject: btrfs: add a btrfs_block_group_root() helper With extent tree v2 we will have a separate root to hold the block group items. Add a btrfs_block_group_root() that will return the appropriate root given the flags of the fs, and convert all functions that need to modify block group items to use the helper.
