[PATCH] return ENOENT from ext3_link when racing with unlink

Browse source

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.
