Subject: 2.6.37, 2.6.38, 2.6.39 vfs/ext3/ext4 crash when unplugging USB storage

Kernel crashes in various interesting ways using this command sequence
with an ext3/ext4 formatted USB storage device (not write-preotected):

	mount /dev/sdb1 /mnt
	cd /mnt
	ls
	# unplug device here
	umount -l -f /mnt
	cd

Reproducable on FC15 live image using the file manager.
