  Modified files:
    sys/kern             vfs_bio.c vfs_cluster.c vfs_subr.c 
    sys/sys              buf.h buf2.h mount.h 
    sys/vfs/ufs          ffs_softdep.c 
  Log:
  Add bio_ops->io_checkread and io_checkwrite - a read and write pre-check
  which gives HAMMER a chance to set B_LOCKED if the kernel wants to write out
  a passively held buffer.
  
  Change B_LOCKED semantics slightly.  B_LOCKED buffers will not be written
  until B_LOCKED is cleared.  This allows HAMMER to hold off B_DELWRI writes
  on passively held buffers.
