    sys/kern             vfs_bio.c 
    sys/sys              buf.h 
    usr.bin/systat       vmstat.c 
  Log:
  Fix hopefully all possible deadlocks that can occur when mixed block sizes
  are used with the buffer cache.  The fix is simply to base the limiting
  and flushing code on a byte count rather then a buffer count.
  
  This will allow UFS to utilizes a greater number of dirty buffers and
  will cause HAMMER to use fewer.  This also makes tuning the buffer cache
  a whole lot easier.
