CVS commit: src/sys/dev

Module Name:    src

Modified Files:
        src/sys/dev: rnd.c

Log Message:
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.
