The current order of unmounting in vfs_unmountall() is that 
volumes are unmounted in opposite order they were mounted, i.e.
leaves are umounted first. While playing with fs staff, I got
many times to the sitation when this order is not very comfortable.
My test volume is normally the last one mounted and when
it's locked up, the kernel never gets to umount other volumes.

It would be cool if the order in which vfs_umountall() umounts
volumes would be switchable. I though about some simple vfs.umountall_lifo
sysctl flag, default on. Do you think such thing would be usable ?
