commit db190d5c850fbe0b4eddccd968f6732cbf2737cd Author: Sepherosa Ziehau <sephe@dragonflybsd.org> Date: Fri Jan 21 13:30:19 2011 +0800 inpcb: Save UDP inpcb into temporary memory during in_pcblist The temorary memory is used later to do the SYSCTL_OUT without the udbinfo serializer being held. Mainly to avoid deadlock triggered by holding serializer and copyout.
