| |
| # In this case, the large-ish selinux attr will create a forkoff |
| # in the temp file smaller than the forkoff in the target file, |
| # because the FMT_EXTENTS attr takes up less space. If there is |
| # no mechanism to grow the temp forkoff to match, we can end up |
| # failing to swap these 2 inodes if the result is not enough |
| # data space in the temp inode as a result. |
