In order for a file to access its own directory entry set, exfat_inode_info(ei) has two copied values. One is ei->dir, which is a snapshot of exfat_chain of the parent directory, and the other is ei->entry, which is the offset of the start of the directory entry set in the parent directory. Since the parent directory can be updated after the snapshot point, it should be used only for accessing one's own directory entry set. However, as of now, during renaming, it could try to traverse or to allocate clusters via snapshot values, it does not make sense. This potential problem has been revealed when exfat_update_parent_info() was removed by commit |
