    sys/kern             vfs_bio.c 
  There is a case when B_VMIO is clear where a buffer can be placed on the
  EMPTY or EMPTYKVA queues without being disassociated from its vnode.
  This can lead to a duplicate logical block panic in the red-black tree code.
  Rework brelse() to ensure that buffers are properly cleaned up before being
  placed on said queues, and add assertions to validate other cases.
