[John Baldwin]

Author: jhb
Date: Wed Dec 10 19:45:58 2008
New Revision: 185874
URL: http://svn.freebsd.org/changeset/base/185874

Log:
  Rather than using a char array with explicit assumptions about the layout
  of 'struct osigevent' in 'struct aiocb', use int and void pointer spare
  members that are identical to 'struct osigevent'.
