15 btrfs: Remove fsid/metadata_fsid fields from btrfs_info
16
17 Currently btrfs_fs_info structure contains a copy of the
18 fsid/metadata_uuid fields. Same values are also contained in the
19 btrfs_fs_devices structure which fs_info has a reference to. Let's
20 reduce duplication by removing the fields from fs_info and always refer
21 to the ones in fs_devices. No functional changes.
