return ENOENT from ext3_link when racing with unlink

It seems the commit below (I've removed the ext4 part that doesn't apply) should also be included in the 2.6.16 branch, or do I miss anything?

TIA
Adrian

[PATCH] return ENOENT from ext3_link when racing with unlink

Return -ENOENT from ext[34]_link if we've raced with unlink and i_nlink is
0. Doing otherwise has the potential to corrupt the orphan inode list, because we'd wind up with an inode with a non-zero link count on the list, and it will never get properly cleaned up & removed from the orphan list before it is freed.
