119 | * We need to check that the format of the data fork in the temporary inode is | |
120 | * valid for the target inode before doing the swap. This is not a problem with | |
121 | * attr1 because of the fixed fork offset, but attr2 has a dynamically sized | |
122 | * data fork depending on the space the attribute fork is taking so we can get | |
123 | * invalid formats on the target inode. | |

128 | * blindly swap data forks on attr2 filesystems. | |

131 | * a corrupt temporary inode, either. | |
132 | * | |
