 Log Message:
 add some (uint64_t) casts so avoid 32 bit overflows.  this fixes my
 3TB disk with 4KB sectors and disklabel (which looks like it would
 work upto 16TB.)
 
 idea from mlel...@.
I think that this small fix should be pulled up to netbsd-4/netbsd-5
branches.

  Log Message:
  Wait for freeing mbuf cluster in sosend() causes freeze network stack.
  Don't wait for it.
  problem was found by iij seil team.
  it is similar to OpenBSD uipc_socket.c rev.1.72.
 
 Can you explain what the actual problem M_WAIT causes i.e. how would
 it freeze network stack?

I don't see what it would solve on the face of it, but regardless M_DONTWAIT
is almost certainly the wrong thing to do here.
