H A Dinvariants18 If $b# points at $bb#, then $bb.e <= b.e < bb.e sub 1#.
20 If $b# points at $bb#, then no other block $b'# with $b'.e = b.e# points at $bb#.
24 and points at $bb# such that $b.e = bb.e#, then no other block $b'# points at $bb#.
26 If $b# is in the active file system and points at $bb# then no other block $b'# in the
27 active file system points at $bb#.
45 Since $b# is open, all the blocks $bb# it points to are also
46 active, and thus they have $bb.e sub 1# set to positive infinity
64 $"BlockRemoveLink" (b -> bb)# removes from block $b# the pointer to $bb#
70 and $b.e = bb.e#, then no other $b'# anywhere
71 points at $bb#, so $bb# can be freed.
