    kernel - Document bkvasync() requirements
    
    * Document that bkvasync() needs to be callable from multiple
      cpus concurrently (aka H2 shared buffering).  The lock has to be
      controlled by the caller (owned by the caller in some way), but the
      owner does not have to be the calling cpu.
