New Revision: 292725
URL: https://svnweb.freebsd.org/changeset/base/292725

Log:
  Unify handles allocation for initiator and target IOCBs.
  
  I am not sure why this was split long ago, but I see no reason for it.
  At this point this unification just slightly reduces memory usage, but
  as next step I plan to reuse shared handle space for other IOCB types.
