 Modified Files:
        src/sys/dev [netbsd-5-0]: rnd.c
 Log Message:
 Pull up following revision(s) (requested by pooka in ticket #948):
        sys/dev/rnd.c: revision 1.74
 rnd_wakeup_readers() uses rndpool_mtx for its own consistency
 management, so it cannot be called with the mutex held.  There is
 no consistency requirement to synchronize over the whole add-and-wakeup
 operation, as if data is consumed in the window the mutex is locked,
 wakeups will simply be skipped.
 fix from Juho Salminen in PR kern/42020.
