(I assume this issue == orphaned inode issue).

ext* doesn't have this issue. If ext* made orphaned inode, ext* doesn't
delete inode from inode table until calling iput() from last referencer.

In FAT case, FAT inode is embedded into dir entry. So, if unlinked inode
(then orphaned inode is detached (fat_detach())), FAT deletes inode (dir
entry) from dir.
