Modified files:
sys/sys queue.h
Log:
Add sanity checking for QUEUE(3) TAILQs under INVARIANTS (similar to
the LIST checks). Races may lead to list corruption, which can be
difficult to unravel in a post-mortem analysis. These checks verify
that the prev and next pointers are consistent when inserting or
removing elements, thus catching any corruption earlier.
