I should add that using umount -i (don't call the umount.<type> helpers)
will successfully workaround the problem, and umount the fs.
Also, with the open-vm-tools-dkms example, the magic def looks like:
/usr/src/open-vm-tools-9.4.6/vmblock/linux/filesystem.h:58:#define
VMBLOCK_SUPER_MAGIC 0xabababab
Which is obviously contrived (they all are I guess), but outside the
kernel provided defines.
Given enough time, I can produce a simple patch, then we would have the
option of raising with upstream, and adding to packages patch list.
