[ Upstream commit 73c34b0b85d46bf9c2c0b367aeaffa1e2481b136 ]
It turns out that I misunderstood the difference between the attr and attr2 feature bits. "attr" means that at some point an attr fork was created somewhere in the filesystem. "attr2" means that inodes have variable-sized forks, but says nothing about whether or not there actually /are/ attr forks in the system.
If we have an attr fork, we only need to check that attr is set.
