Subject: Btrfs: use set_nlink if our i_nlink is 0
From: Josef Bacik <jbacik@xxxxxxxxxxxx>
commit 9bf7a4890518186238d2579be16ecc5190a707c0 upstream.
We need to inc the nlink of deleted entries when running replay so we can do the
unlink on the fs_root and get everything cleaned up and then have the orphan
cleanup do the right thing. The problem is inc_nlink complains about this, even
thought it still does the right thing. So use set_nlink() if our i_nlink is 0
to keep users from seeing the warnings during log replay. Thanks,
