Hi all,

After merging the btrfs tree, today's linux-next build (x86_64 allmodconfig)
failed like this:

fs/btrfs/disk-io.c: In function 'btrfs_init_fs_root':
fs/btrfs/disk-io.c:1531:22: warning: unused variable 'nofs_flag' [-Wunused-variable]
 1531 |         unsigned int nofs_flag;
      |                      ^~~~~~~~~

Caused by commit

  1556cd3d099a ("btrfs: locking: use atomic for DREW lock writers")

I have used the btrfs tree from next-20230112 for today.
