Sorry for lacking details.

Yes, I use JFFS2. 
If you mount a device with a file on JFFS2, a dirent node and a dnode are alloced.
But upper layer does not issue, jffs2_clear_inode for an inode of the dnode during unmount.
You can see it just by free command if my implementation is not wrong.

Best regards.
