  Modified files:
    sys/kern             vfs_bio.c 
  Add two checks for potential buffer cache races.
  "Warning buffer %p (vp %p lblkno %d) was recycled"
      Occurs if a buffer is recycled unexpectedly.  The code will print this
      warning and retry if it detects the case.
  "Warning invalid buffer %p (vp %p lblkno %d) did not have cleared b_blkno cache"
      Occurs if a B_INVAL buffer's b_blkno cache has not been reset.  The
      code will reset the cache if it detects this case.
