  Modified:    sys/kern  vfs_cluster.c vfs_bio.c
               sys/sys   buf.h
  Log:
  General fixes to the vfs clustring code:
  
  1) Make cluster buffer list be a non-malloced chain.  This eliminates
  yet another 'evil' M_WAITOK and generally cleans up the code.
  2) Fix write clustering for ext2fs.  It was just broken.  Also, ffs
  clustering had an efficiency problem that more bawrites were happening
  than should have been.
  3) Make changes to buf.h to support the above, plus remove b_pfcent
  at the request of David Greenman.

  Note that the reallocblocks code is disabled pending rewrite for
  the cluster buffer list changes.
