Log:
MFC: Change the interface to vflush() so that it can deal with
extra references on the filesystem root vnode. This fixes bugs in
a number of filesystems that could cause forced umounts to erroneously
return EBUSY, and it centralises a lot of xxx_unmount logic.
This unfortunately requires the recompilation of any filesystem
KLDs, although I have added an extra sanity check that should help
to avoid panics if old modules are used (the filesystem may refuse
to umount, and if so, a warning message will appear on the console).
Not objected to by: -stable
