Modified files:
sys/sys kernel.h eventhandler.h
sys/kern subr_eventhandler.c
Log:
- Convert the per-eventhandler list mutex to a lockmgr lock so that it can
be safely held across an eventhandler function call.
- Fix an instance of the head of an eventhandler list being read without
the lock being held.
- Break down and use a SYSINIT at the new SI_SUB_EVENTHANDLER to initialize
the eventhandler global mutex and the eventhandler list of lists rather
than using a non-MP safe initialization during the first call to
eventhandler_register().
- Add in a KASSERT() to eventhandler_register() to ensure that we don't try
to register an eventhandler before things have been initialized.
