321	Could not unmount FAT after `mv`	Jakub Jermář	Jakub Jermář	"The `mv` command is expected to fail on FAT because FAT does not support multiple hard links. However, attempting to rename a file residing on a FAT file system will result in rendering that file system not unmountable. How to reproduce on a TMPFS root file system:

{{{
/ # cd /tmp
/tmp # mkfile -s 2m image
/tmp # file_bd image fbd0
/tmp # mkfat fbd0
/tmp # fat
/tmp # mount fat /data fbd0
/tmp # cp /readme /data/r
/tmp # mv /data/r /data/r1
/tmp # unmount /data
}}}

`unmount` will report EBUSY (-15)."	defect	closed	major	0.4.3	helenos/srv/vfs		fixed
