odd VFS message

After upgrading to kernel 2.1.57, I began getting this message whenever I
do 'umount /dev/hdb1', an MSDOS FAT partition:

Sep 28 00:05:32 metroid kernel: VFS: Busy inodes after unmount. Self-destruct
in 5 seconds. Bye-bye..

This message never appeared before 2.1.57, does not appear on umount'ing
of other FAT partitions, and a quick reboot to DOS and a run of NDD shows
no errors on the drive, so apparently VFS was exaggerating about the
self-destruct part. :)

So what is it that VFS is trying to tell me here?
